[FLASH-USERS] [EXT] fixing layers

[Thibault Goudal]

Hey Eddie, 
Do you know if there's an example of the F90 files that could include such adjustements?

In FLASH, we have BDRY_VAR to solve this issue. If you set certain cells BDRY_VAR = 1.0, then the code will see these cells as "solid" and they won't expand into a "vacuum" region. If you want to allow them to expand at a later time, then you will have to make adjustments to BDRY_VAR in Simulation_adjustEvolution.

Hi guys, 
After fixing my mesh reconstruction, I've noticed that if I irradiate a single layer with a vaccum volume behind, there's some expansion in this vacuum before any shock breaks out. 
If I want to design an experiment with an initial solid target, I would like this material to be freezed. I discused with Hydra users and it came up that they use a special mode called "Quiet Start" to fix the solid materials but I don't know if we have such a tool on FLASH. 
Does anybody know how we could solve this issue?
