[FLASH-USERS] First time using Laser Slab in FLASH + Additional ionmix4 files

[Hansen, Eddie]

Hi Izzy,

There are example par files included in the LaserSlab directory that you can start with, and many of them include a comment at the top for a ./setup command. There are also several different ionmix files to get you started. You might find others in other problem directories. You would need a copy of IONMIX software to generate your own tables.

For what it’s worth, I typically keep my object directory and run directories separate. So I’ll compile FLASH in the object directory, then copy over the executable, par file, EOS tables, and any other input files to a separate run directory (often in a scratch space on a HPC system).

Subject: [FLASH-USERS] First time using Laser Slab in FLASH + Additional ionmix4 files
Good morning FLASH users,

In short:
- Please can somebody advise me on the structure I should use for the setup line the first time I run the laser slab example in FLASH? Especially regarding the parameter file, do I need to create this or is it included?
- Please can somebody advise how I can find additional ionmix4 files (i.e for copper) and use them in the simulation?

I'm trying to build up from the laser slab example provided by FLASH. I have yet to run it for the first time; is there any advice people have for before I do this? Especially with regards to the setup line? Do I need to create a parameter file before running it for the first time? or does one already exist for the laser-slab simulation?

Once I have run it successfully for the example problem of the laser slab, the first perturbation I want to make is to change the material of the target. Please can somebody advise how to find additional ionmix4 files and then use them in the simulation?

Kind regards and thank you in advance for any advice,
Izzy
