# HeLaZ (Hermite-Laguerre Z-pinch solver, 2021)
To compile it check INSTALLATION.txt
How to run it
1. Be sure to have correct paths in local/dirs.inc for the different libraries
2. Compile from HeLaZ/ using make
3. To run the code, use HeLaZ/wk/local_run.m and run it to set up the parameters and the results folder
4. Then go to the results folder and launch HeLaZ using mpirun -np num_procs ./../../../bin/helaz num_p num_kr
5. You can obtain various plots and gifs using HeLaZ/wk/analysis_2D.m once the simulation is done. To select the correct output file, run parameters*.m with the corresponding simulation parameters and then run analysis_2D.m (everything with matlab from wk/)
// Comment : For some collision operators (Sugama and Full Coulomb) you have to run COSOlver from B.J.Frei first in order to generate the required matrices in HeLaZ/iCa folder.
