[FLASH-USERS] Laser Slab 2d adding a physical mesh

[Patrick Cappello]

Dear Flash users, 

I am trying to setup an HEDP problem using lasers and I want to add a physical grid that would create fluctuations in a plasma flow. How could I add this to the problem setup? 

I’m currently running the laser slab problem with a slightly modified example.par with a polystyrene slab and I’m having trouble adding an additional species to the problem. 
Is there a different .par file that could setup something like this? 

Any help is appreciated. 
Thank you
