Tutorial: Simulation Analysis

This repository contains example parameter files to illustrate how to use some of the most common diagnostic thorns in the Einstein Toolkit, such as AHFinderDirect and QuasiLocalMeasures. The parameter files do not tell the whole story, and they are likely very different from the ones you will use to perform production-quality simulations. Nevertheless, they were constructed using only a minimal number of thorns which are required to perform the basic tasks they are setup to do. Because of this, we hope they are significantly shorter (and more organized) than typical parameter files, and we thus hope they will be of valuable use to new users of the Einstein Toolkit.

This repository also contains scripts for processing simulation data. In particular, we illustrate how to create movies of the density $\rho$ and the radial velocity $v^{r}$, using kuibit to do most of the heavy lifting during the post-processing stage. While kuibit (and in particular motionpicture) can be used to generate the movies, we have not done it on the scripts because, from experience, most high-performance computing systems do not have ffmpeg installed. We thus opt to combine the images into a movie in a separate step.
