Summer Einstein Toolkit Workshop 2013

The users workshop is part of the CGWAS and will be held on the last day of the summer school (Friday). Currently the programme lists introduction to numerical relativity, an introduction to the ET and two hands-on sessions. The big hands-on session from last year was too technical and should be reworked if used at all. Instead we could consider running a very short head-on nsns run and analysing the data. The runs takes ~20min at a ridiculously low resolution, but might be sufficient to shows how it's done.

Hands on exercises

Running and extending (par-file) of two provided examples: perturbed, single BH, and perturbed, single TOV star
Hands-on: Using visualization tools to look at meaningful quantities ( TOV profile evolutions ) (slides)
Create movie of either BH+GW or TOV oscillations using VisIt (slides, TOV session file, TOV data file, Psi4 session file, Psi4 data file)
Hands-on: Implement your own thorn (neutron star tracking), and visualize it, in teams of about 5 people (, more information at end of wiki
