Adding Llama to the ET
In order to add Llama to the ET, we require:
- Tests
- Documentation
- Example(s)
Tests
We have three test cases:
- Llama/Coordinates/test/test7patch: Sets up the 7-patch system. Checks coordinates. Makes sure that this doesn't crash. No evolution.
- Llama/LlamaWaveToy/test/llamawavetoy_6patch.par: Sets up 6-patch (spherical) system. Evolves l=2,m=2 x Gaussian for 4 iterations. Checks 1D ASCII output. Runs on any number of processes (only 1 and 2 have been tested).
- Llama/LlamaWaveToy/test/llamawavetoy_7patch.par: Same as 6-patch but uses 7-patch system. Works on 1 process. Currently has a problem on 2 processes; looks like a bug. Assertion failure from Carpet. Restricted to run on 1 process as a result.
Documentation
The following thorns have documentation:
Examples
There are three examples in LlamaWaveToy/par:
- Kerr-Schild_Gaussian.par: Radial Gaussian evolved with wave equation on Kerr-Schild background. Uses 6-patch (spherical) system.
- Kerr-Schild_Multipole.par: l=2, m=2 mode with radial Gaussian evolved on a Kerr-Schild background. Uses 6-patch (spherical) system.
- Minkowski_Multipole.par: l=2, m=2 mode with radial Gaussian evolved on a flat background. Uses 7-patch (spherical+Cartesian) system.
These run in about 20 minutes on a laptop, and evolve a wave on a given background. These have been tested and work.
The Kerr-Schild_Multipole example is shown on a new gallery page.
There is also the GW150914 example on the gallery page.
