<p>Bentivegna: /* First call: Friday, 9th February 2018, 10pm UTC (4pm CST / Saturday 7am JST) */</p> <hr /> <div>'''Working Group: Cosmology and Particles'''<br /> <br /> '''Date Approved:''' December 4th, 2017<br /> <br /> '''Leads:''' Eloisa Bentivegna, Helvi Witek<br /> <br /> '''Background:''' The study of relativistic effects and strong-field dynamics is playing an increasingly important role in many disciplines related to, but not necessarily overlapping with, gravitational-wave astronomy. The full numerical integration of Einstein’s equation has now been adopted to describe structure formation in the late Universe, high-energy processes near black holes, gravitational-wave emission by exotic objects, and many other phenomena. However, numerical implementations of extensions to GR -- be it in the form of additional fields serving as dark matter candidates, more involved extensions motivated by quantum gravity paradigms or novel initial conditions for inflation -- are still scarce. Many of these effects are expected to be testable with advanced LIGO/Virgo or the space-based LISA mission. In order to match theory with observations it is crucial to prepare the necessary waveform models, which is one of the goals of this working group.<br /> <br /> This Working Group should serve as the first arena to discuss extensions of Numerical Relativity towards new physical applications and their implementation in the Einstein Toolkit, enabling the modelling of these spacetimes beyond the traditional canons of GW-related NR. Given the exploratory character of many of these applications, the discussion will include not only algorithmic and infrastructural aspects, but also foundational issues connected to the physical and mathematical traits of the theories involved (such as how to best formulate the constitutive equations, construct initial data, define observables, and so on).<br /> <br /> '''Activities:''' The Working Group will hold a monthly or bimonthly brainstorming call. Practical developments arising from the discussions may be subsequently formalized as Development Teams and attached to this WG’s activities. The calls may also contain short seminars. The development of an interface to the many experiments and observational missions within the WG’s scope should be among the top priorities.<br /> <br /> '''Milestones:''' The main objective of this Working Group is that of collecting all the interested parties in a single community, give it an official structure, promote brainstorming and knowledge-sharing in this vast new field, and provide a public interface to the growing number of non-GW relativists who are turning to the Einstein Toolkit to extend the reach of their investigations in their respective fields.<br /> <br /> '''Deliverables:''' This WG will deliver a yearly document, representing the Group’s outlook on the year’s developments in the field such as major publications, conferences, code releases, grant awards and their possible ramifications, the topics discussed during the calls, and any other issue of interest. This document will be the standard reference both for existing ETers looking to join new projects and for new members from other areas of Theoretical Physics where the ET may be employed.<br /> Furthermore, we expect new add-ons to the Einstein Toolkit as deliverables of this working group. Ensuring the quality and and performance of these thorns, as well as cross-checking new code, will be part of the WG’s responsibility.<br /> <br /> '''Engagement:''' New members can join the working group by subscribing to the mailing list [mailto:cosmoparticle-wg@einsteintoolkit.org cosmoparticle-wg@einsteintoolkit.org].<br /> <br /> == Working group calls ==<br /> '''Link for the calls:'''<br /> https://hangouts.google.com/hangouts/_/tce4j4gzcfcormnadoauiqcvg4e<br /> <br /> * Friday, 9th February 2018, 10pm UTC (4pm CST / Saturday 7am JST): [[WGCPcall20180209 | agenda and minutes]]</div>

This tool uses PAPI and CactusTimers to generate a graphical output (html) of Cactus performance.<br /> * Is it time for a new release of Cactus? The lack of new releases led at least one online user to conclude that Cactus was a dead project. Perhaps we should have a new Cactus release with each release of the ET?<br /> * Creation of a popular book about the science done by the Einstein Toolkit (Steven) -- I was thinking about ways to improve the visibility of the platform and attract new users and/or funding. Coincidentally, I've recently had some experience figuring out how to publish books on various platforms. These days it's fairly straightforward to publish books with no cost as paperback and ebook, or even hardcover. I was thinking that many of the people working on the ET could write a chapter, and I could handle the publishing. One can configure any level of profit for such endeavors, and I would like to suggest zero, since there are probably legal issues with the toolkit actually making money from such a thing. Does this sound like something people would be interested in?<br /> * switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> <br /> Meeting minutes are [http://lists.einsteintoolkit.org/pipermail/users/2017-September/005769.html here].<br /> <br /> == 28-Aug-2017 ==<br /> * Status update on KNL<br /> * update on Euro ET workshop in Mallorca, Oct 11-14, http://grg.uib.es/EinsteinToolkit2017/<br /> * status of servers at LSU<br /> ** continued use of svn<br /> ** switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 21-Aug-2017 ==<br /> * Progress on tutorial machine at NCSA<br /> * Comments/discussion on updates to the Working Group Document (including procedures) (Gabrielle) https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 14-Aug-2017 ==<br /> * Report on ET workshop survey (Nasir Eisty)<br /> * NSF SI2 Project posted (Gabrielle Allen) https://figshare.com/articles/Einstein_Toolkit_Community_Integration_and_Data_Exploration/5306587<br /> * Template for working groups: https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs/edit?usp=sharing<br /> * Discuss new code contributions<br /> ** RNSID<br /> <br /> == 07-Aug-2017 ==<br /> <br /> * Report from summer school and workshop:<br /> ** Summer school recordings etc. are here: https://docs.einsteintoolkit.org/et-docs/NCSAETK2017/setup<br /> * Introduce working groups<br /> * Discuss new code contributions<br /> ** GiRAFFE<br /> ** RNSID<br /> * DataVault updates<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005706.html</div>

<p>Bentivegna: </p> <hr /> <div>'''Working Group: Cosmology and Particles'''<br /> <br /> '''Date Approved:''' December 4th, 2017<br /> <br /> '''Leads:''' Eloisa Bentivegna, Helvi Witek<br /> <br /> '''Background:''' The study of relativistic effects and strong-field dynamics is playing an increasingly important role in many disciplines related to, but not necessarily overlapping with, gravitational-wave astronomy. The full numerical integration of Einstein’s equation has now been adopted to describe structure formation in the late Universe, high-energy processes near black holes, gravitational-wave emission by exotic objects, and many other phenomena. However, numerical implementations of extensions to GR -- be it in the form of additional fields serving as dark matter candidates, more involved extensions motivated by quantum gravity paradigms or novel initial conditions for inflation -- are still scarce. Many of these effects are expected to be testable with advanced LIGO/Virgo or the space-based LISA mission. In order to match theory with observations it is crucial to prepare the necessary waveform models, which is one of the goals of this working group.<br /> <br /> This Working Group should serve as the first arena to discuss extensions of Numerical Relativity towards new physical applications and their implementation in the Einstein Toolkit, enabling the modelling of these spacetimes beyond the traditional canons of GW-related NR.

This tool uses PAPI and CactusTimers to generate a graphical output (html) of Cactus performance.<br /> * Is it time for a new release of Cactus? The lack of new releases led at least one online user to conclude that Cactus was a dead project. Perhaps we should have a new Cactus release with each release of the ET?<br /> * Creation of a popular book about the science done by the Einstein Toolkit (Steven) -- I was thinking about ways to improve the visibility of the platform and attract new users and/or funding. Coincidentally, I've recently had some experience figuring out how to publish books on various platforms. These days it's fairly straightforward to publish books with no cost as paperback and ebook, or even hardcover. I was thinking that many of the people working on the ET could write a chapter, and I could handle the publishing. One can configure any level of profit for such endeavors, and I would like to suggest zero, since there are probably legal issues with the toolkit actually making money from such a thing. Does this sound like something people would be interested in?<br /> * switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> <br /> Meeting minutes are [http://lists.einsteintoolkit.org/pipermail/users/2017-September/005769.html here].<br /> <br /> == 28-Aug-2017 ==<br /> * Status update on KNL<br /> * update on Euro ET workshop in Mallorca, Oct 11-14, http://grg.uib.es/EinsteinToolkit2017/<br /> * status of servers at LSU<br /> ** continued use of svn<br /> ** switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 21-Aug-2017 ==<br /> * Progress on tutorial machine at NCSA<br /> * Comments/discussion on updates to the Working Group Document (including procedures) (Gabrielle) https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 14-Aug-2017 ==<br /> * Report on ET workshop survey (Nasir Eisty)<br /> * NSF SI2 Project posted (Gabrielle Allen) https://figshare.com/articles/Einstein_Toolkit_Community_Integration_and_Data_Exploration/5306587<br /> * Template for working groups: https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs/edit?usp=sharing<br /> * Discuss new code contributions<br /> ** RNSID<br /> <br /> == 07-Aug-2017 ==<br /> <br /> * Report from summer school and workshop:<br /> ** Summer school recordings etc. are here: https://docs.einsteintoolkit.org/et-docs/NCSAETK2017/setup<br /> * Introduce working groups<br /> * Discuss new code contributions<br /> ** GiRAFFE<br /> ** RNSID<br /> * DataVault updates<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005706.html</div>

This tool uses PAPI and CactusTimers to generate a graphical output (html) of Cactus performance.<br /> * Is it time for a new release of Cactus? The lack of new releases led at least one online user to conclude that Cactus was a dead project. Perhaps we should have a new Cactus release with each release of the ET?<br /> * Creation of a popular book about the science done by the Einstein Toolkit (Steven) -- I was thinking about ways to improve the visibility of the platform and attract new users and/or funding. Coincidentally, I've recently had some experience figuring out how to publish books on various platforms. These days it's fairly straightforward to publish books with no cost as paperback and ebook, or even hardcover. I was thinking that many of the people working on the ET could write a chapter, and I could handle the publishing. One can configure any level of profit for such endeavors, and I would like to suggest zero, since there are probably legal issues with the toolkit actually making money from such a thing. Does this sound like something people would be interested in?<br /> * switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> <br /> Meeting minutes are [http://lists.einsteintoolkit.org/pipermail/users/2017-September/005769.html here].<br /> <br /> == 28-Aug-2017 ==<br /> * Status update on KNL<br /> * update on Euro ET workshop in Mallorca, Oct 11-14, http://grg.uib.es/EinsteinToolkit2017/<br /> * status of servers at LSU<br /> ** continued use of svn<br /> ** switch ExternalLibraries over to github: svn checkout https://github.com/rhaas80/GSL<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 21-Aug-2017 ==<br /> * Progress on tutorial machine at NCSA<br /> * Comments/discussion on updates to the Working Group Document (including procedures) (Gabrielle) https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005739.html<br /> <br /> == 14-Aug-2017 ==<br /> * Report on ET workshop survey (Nasir Eisty)<br /> * NSF SI2 Project posted (Gabrielle Allen) https://figshare.com/articles/Einstein_Toolkit_Community_Integration_and_Data_Exploration/5306587<br /> * Template for working groups: https://docs.google.com/document/d/1j12IEY8kH6R33qfXpD5BaDDXLEYdNceEqf9crLupsPs/edit?usp=sharing<br /> * Discuss new code contributions<br /> ** RNSID<br /> <br /> == 07-Aug-2017 ==<br /> <br /> * Report from summer school and workshop:<br /> ** Summer school recordings etc. are here: https://docs.einsteintoolkit.org/et-docs/NCSAETK2017/setup<br /> * Introduce working groups<br /> * Discuss new code contributions<br /> ** GiRAFFE<br /> ** RNSID<br /> * DataVault updates<br /> Minutes: http://lists.einsteintoolkit.org/pipermail/users/2017-August/005706.html</div>

<p>Bentivegna: /* Obstacles faced by new users */</p> <hr /> <div>== Summary ==<br /> <br /> We would like to improve the experience of new users of the Einstein Toolkit. Some of us will work on this at the North American Einstein Toolkit workshop in August 2017.<br /> <br /> If you have suggestions for improvements, or things which don't work well right now, please add them below.<br /> <br /> We probably won't have time during the 2-day workshop to address all that is listed here, but we will make an effort to make progress on one or two items.<br /> <br /> == Brainstorming ==<br /> <br /> === Obstacles faced by new users ===<br /> <br /> * The ET takes a long time to compile<br /> ** Maybe have multiple thornlists<br /> * The ET has a lot of dependencies, or compiles a lot of libraries (which sometimes don't compile successfully)<br /> ** Is the self-built version of OpenMPI ever actually usable?<br /> ** Erik has talked about using Spack for libraries. Maybe we should push for this.<br /> * Many of the examples do not work<br /> ** At a previous workshop, this was evaluated, but there was no resolution ([[Fixing examples]])<br /> * There are too many tutorials<br /> ** The following are listed on the wiki:<br /> *** [[Tutorial for New Users]]<br /> *** [[Simplified Tutorial for New Users]]<br /> *** [[Getting Started for Cactus Experts]]<br /> *** [[Compiling the Einstein Toolkit]]<br /> ** The names of the tutorials do not allow users to distinguish what they are for. For example, the Tutorial for New Users and Simplified Tutorial for New Users differ in that the former is run on Queen Bee, and the latter is run on a user's own laptop or workstation. <br /> ** Perhaps all the above should be consolidated<br /> * Configuring the ET on a new machine is very difficult (even just compiling, let along interactions with queuing systems etc)<br /> * On slower laptops, the build stage regularly hangs and has to be killed and restarted (which almost always solves the problem). Can we figure out which components are responsible, and omit them from quick-start tutorials?</div>

<p>Bentivegna: /* Prerequisites */</p> <hr /> <div>Here you will find a step by step guide to downloading, installing, and running the Einstein Toolkit. For a more detailed tutorial, view the [[Tutorial for New Users]].<br /> <br /> ==Prerequisites==<br /> <br /> You will need a number of packages installed in order to download the Einstein Toolkit components, and if you follow the instructions in this tutorial. Instructions for the installation of such packages can be found at the beginning of each optionlist. <br /> <br /> For instance, on a Fedora-based system, the user is instructed to first run:<br /> <br /> yum -y install mpich2 mpich2-devel \<br /> gsl gsl-devel libjpeg-devel hdf5 hdf5-devel \<br /> gcc gcc-c++ gcc-gfortran patch \<br /> numactl-devel hdf5-mpich-devel \<br /> numactl hwloc subversion \<br /> git openssl-devel lapack-static<br /> <br /> Please check the optionlist that is relevant for your system and make sure all required packages are installed before proceeding with the next step.<br /> <br /> ==Downloading==<br /> <br /> A script called GetComponents is used to fetch the components of the Einstein Toolkit. GetComponents serves as convenient wrapper around lower level tools like git and svn to download the codes that make up the Einstein toolkit from their individual repositories. You may download and make it executable it as follows:<br /> <br /> curl -O -L https://raw.githubusercontent.com/gridaphobe/CRL/ET_2015_11/GetComponents<br /> chmod a+x GetComponents<br /> <br /> GetComponents accepts a thorn list as an argument. To check out the needed components:<br /> <br /> ./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2015_11/einsteintoolkit.th<br /> <br /> which downloads the master thorn list from the Einstein toolkit server and proceeds to download all thorns.<br /> This thornlist checks out Cactus, the Einstein Toolkit, and Simulation Factory.<br /> <br /> ==Configuring==<br /> <br /> You may proceed to configure Simfactory which requires some changes for some OS.<br /> <br /> cd Cactus<br /> <br /> # for Debian<br /> ./simfactory/bin/sim setup --optionlist=debian.cfg --runscript debian.sh<br /> # for Ubuntu, Mint<br /> ./simfactory/bin/sim setup --optionlist=ubuntu.cfg --runscript debian.sh<br /> # for Fedora (you may have to log out and back in if you have just intalled mpich to make the module command work)<br /> module load mpi<br /> ./simfactory/bin/sim setup --optionlist=fedora.cfg --runscript debian.sh<br /> <br /> # OSX+MacPorts (last tested with Yosemite)<br /> ./simfactory/bin/sim setup --optionlist=osx-macports.cfg --runscript osx-macports.run<br /> # OSX+Homebrew (last tested with Yosemite)<br /> export CPATH=/usr/local/include LIBRARY_PATH=/usr/local/lib<br /> ./simfactory/bin/sim setup --optionlist=osx-homebrew.cfg --runscript generic-mpi.run<br /> <br /> Accept the default values for all options.<br /> <br /> ==Building==<br /> <br /> Now that you have configured Simfactory, you may build:<br /> <br /> ./simfactory/bin/sim build --mdbkey make 'make -j2' --thornlist=manifest/einsteintoolkit.th<br /> <br /> Adjust <nowiki>-j2</nowiki> to match the number of cores your machine possesses if you want to use more or less than 2 parallel build processes. This may take a while, as it compiles all the thorns specified in manifest/einsteintoolkit.th.<br /> <br /> ==Running==<br /> The example files provided are mostly too large to run on a single machine. You can try however to run the static_tov example which is smallest and requires about 1.3GB of RAM to run and will run for about 24 hours using a single core. To speed up the run, you can try and reduce the resolution by increasing the parameters "CoordBase::dx", "CoordBase::dy", and "CoordBase::dz" from 8 to 12 which will reduce runtime to roughly 5 hours and memory consumption to 800MB. <br /> <br /> # modify parameter file for smaller memory footprint using sed<br /> sed '/CoordBase::d[xyz]/s/8/12/' <par/static_tov.par >par/static_tov_small.par<br /> # start simulation, watch log output<br /> ./simfactory/bin/sim submit static_tov --parfile=par/static_tov_small.par --procs=1 --walltime=8:0:0<br /> ./simfactory/bin/sim show-output --follow static_tov<br /> <br /> Cactus will use a sinlge MPI process and (unless you have set OMP_NUM_THREADS) will use as many OpenMP threads as you have cores on your computer. Under Linux use can use <code>top -H</code> to show all running threads.<br /> <br /> ==Look at Results==<br /> <br /> When the simulation is complete (ie. when "All done" appears in the output), stop simfactory by pressing CTRL-C and move to the output directory. The command should be:<br /> <br /> cd ~/simulations/static_tov/output-0000/static_tov_small<br /> <br /> You should see a number of files with the extenstion ''.asc''. These are 0-D <br /> (reductions of 3-D grid functions to scalar values) and 1-D ASCII output files that<br /> can be plotted with gnuplot. <br /> <br /> In this case it's interesting to look at the maximum of the density (in the file hydrobase-rho.maximum.asc). Start gnuplot with the command:<br /> <br /> gnuplot<br /> <br /> and at the gnuplot prompt type:<br /> <br /> plot 'hydrobase-rho.maximum.asc' using 2:3 with linespoints<br /> <br /> This plots the data in column 3 (rho) as a function of the data in column 2 (time).<br /> <br /> [[Image:Rho_of_time_lowres.png]]<br /> <br /> As can be seen from the plot, the maximum of the density oscillates with decreasing amplitude around the initial value with a small drift upwards. Even though the initial model is supposed to be in equilibrium, numerical errors means that the numerical model is not exactly in equilibrium and it starts to oscillate. The oscillation energy is slowly dissipated by shocks, decreasing the oscillation amplitude, while the star contracts in response, increasing the maximum density.<br /> <br /> A consistent picture can be seen by plotting the minimum of the lapse:<br /> <br /> p 'admbase-lapse.minimum.asc' u 2:3 w lp<br /> <br /> [[Image:Lapse_of_time_lowres.png]]<br /> <br /> The quantity shows the same features as the maximum of the density, except the drift is downwards. The downwards trend stems from the contraction of the star. As the star contracts, the curvature of spacetime increases slightly. In response, the singularity avoiding lapse condition used here decreases the lapse.<br /> <br /> As the oscillations and subsequent drift of the density and the lapse are caused by numerical error, increasing the numerical resolution will decrease these effects.<br /> <br /> ==Further reading==<br /> The following resources provide more in-depth explanations of the tools and concepts used in this tutorial<br /> * [http://einsteintoolkit.org/documentation/UsersGuide/UsersGuide.html Cactus users guide] containing detailed information on a thorn structure and the support routines offered by Cactus.

On Linux, this will download a tarball containing a directory<br /> <br /> visit<version number>.<architecture><br /> <br /> Changing to this directory, the command<br /> <br /> bin/visit<br /> <br /> will launch the software.<br /> <br /> On Mac OS X, a .dmg file will be downloaded first, containing the <tt>VisIt.app</tt> executable.<br /> <br /> ==Opening the databases==<br /> <br /> Once the software is running, the button <tt>Open</tt> can be used to open files from the simulation.<br /> <br /> [[Image:vt-1.png]]<br /> <br /> If you are using the Simulation Factory to launch and manage the run, the data will be output under the directory <tt><basedir>/<simulation name>/output-<nnnn>/<parfile name></tt>, where <tt><nnnn></tt> is the number of the restart. There are essentially two types of files that can be visualised with VisIt:<br /> <br /> * Files from the thorn <tt>CarpetIOHDF5</tt>, with .h5 extension, which will be read by the CarpetHDF5 plugin in VisIt and represent the 1D, 2D, or 3D configuration of a specific field, on a number of constant-time spaces;<br /> * Files from the thorn <tt>QuasiLocalMeasures</tt>, with .vtk extension, which are read natively by <tt>VisIt</tt> and represent the shape and properties of relevant 2D topological spheres, such as the apparent horizons, also at different times;<br /> <br /> ==A visualization example==<br /> <br /> Let us, for instance, plot the configuration of the conformal factor <tt>ML_BSSN::phi</tt> on the xy plane, and superimpose the apparent horizon shapes. We first need to load the data for the conformal factor on this plane, using the Open button and selecting the correct path for the database <tt>phi.*.xy.h5</tt>.

To create the database, we need to use the menu <tt>Controls > Database correlations</tt>, select <tt>New…</tt>, select the three databases on the left window (<tt>Sources</tt>) and move them right using the right arrow.

On Linux, this will download a tarball containing a directory<br /> <br /> visit<version number>.<architecture><br /> <br /> Changing to this directory, the command<br /> <br /> bin/visit<br /> <br /> will launch the software.<br /> <br /> On Mac OS X, a .dmg file will be downloaded first, containing the `VisIt.app` executable.<br /> <br /> ==Opening the databases==<br /> <br /> Once the software is running, the button [tt]Open[/tt] can be used to open files from the simulation.<br /> <br /> [[Image:vt-1.png]]<br /> <br /> If you are using the Simulation Factory to launch and manage the run, the data will be output under the directory <basedir>/<simulation name>/output-<nnnn>/<parfile name>, where <nnnn> is the number of the restart. There are essentially two types of files that can be visualised with VisIt:<br /> <br /> 1. Files from the thorn `CarpetIOHDF5`, with .h5 extension, which will be read by the CarpetHDF5 plugin in VisIt and represent the 1D, 2D, or 3D configuration of a specific field, on a number of constant-time spaces;<br /> 2. Files from the thorn `QuasiLocalMeasures`, with .vtk extension, which are read natively by `VisIt` and represent the shape and properties of relevant 2D topological spheres, such as the apparent horizons, also at different times;<br /> <br /> ==A visualization example==<br /> <br /> Let us, for instance, plot the configuration of the conformal factor `ML_BSSN::phi` on the xy plane, and superimpose the apparent horizon shapes. We first need to load the data for the conformal factor on this plane, using the Open button and selecting the correct path for the database `phi.*.xy.h5`. We can then generate the plot by clicking `Add > Pseudocolor > ML_BSSN--phi`. If the `Auto Apply` feature in `VisIt` is not selected, we need to click on `Draw` to make the plot appear.<br /> <br /> [[Image:Vt-2.png]]<br /> <br /> [[Image:vt-3.png]]<br /> <br /> [[Image:vt-4.png]]<br /> <br /> If necessary, we can tune the colormap until the plot looks like the one below (this result has been obtained by selecting the `Plot Attributes > Pseudocolor...` menu and choosing a `Skew` value of 1000):<br /> <br /> [[Image:vt-5.png]]<br /> <br /> Next, we can plot the horizon surface of the first black hole by opening the `surface01_*.vtk` database, and using `Add > Mesh > mesh`. We can similarly add the second horizon by following the previous steps for the `surface02_*.vtk` database.<br /> <br /> [[Image:vt-6.png]]<br /> <br /> [[Image:vt-7.png]]<br /> <br /> [[Image:vt-8.png]]<br /> <br /> The plot depicts now the system’s conformal factor and horizons at t=0. To cycle through subsequent times, we need to create a database correlation first, telling `VisIt` how to match the time indices in the `phi.*.xy.h5`, `surface01_*.vtk`, and `surface02_*.vtk`. To create the database, we need to use the menu `Controls > Database correlations`, select `New…`, select the three databases on the left window (`Sources`) and move them right using the right arrow. Once the databases appear in the `Correlated sources` window, we can name the correlation, select `Cycle` for the correlation method, and click `Create database correlation`. Once the correlation is created, an `Active time slider` menu will appear just below the `Active Source` menu, indicating that our correlation is now controlling the slider; moving this slider will then step through the three databases simultaneously, making sure that all the plotted data refers to the same time coordinate.<br /> <br /> `VisIt` provides a number of tools and options to tune this visualization, output it to image or movie files, save and restore sessions, remote visualization, and so on.
