Evrard Collapse problem parameters

[HamidGadirov]

Hi,

I am working with Evrard Collapse problem (https://github.com/AMReX-Astro/Castro/tree/main/Exec/gravity_tests/evrard_collapse) and wanted to ask which parameters can be changed within simulation so that to generate an ensemble (runs with different parameters so that to have variations in data).

I am especially interested in density and velocity fields. Is it possible to change parameters so that the data generated by the simulation is a bit different? If that is not possible, could you recommend other simulations from Castro?

Thanks!
Hamid

Hamid, what is your goal? Are you actually interested in the Evrard problem? or do you just want something that can generate a lot of variation in the simulation? Evrard is not something we run much and really is a test problem, so not very visually interesting.

No, I don't necessarily need to use the Evrard problem. I need to generate an ensemble (runs of simulation with different parameters so that there are variations in data). I need scalar and vector data, so the variations in density and velocity fields depending on the parameters are the best. Which simulation can you recommend? Thanks!
