[FLASH-USERS] How to make laser ignore hydro boundary conditions

[Reyes, Adam]

Hi Yanfei,

You shouldn’t need to do anything else. Taking the provided laserslab setup and changing the XR boundary to reflecting and setting ed_ignoreBoundaryCondition_1=.true. gives the expected result:



You can see the rays enter the right reflecting boundary and then reflect again when they return.

I see that if I want to set the hydro boundary condition to "reflect", that is, set "xr_boundary_type = "reflect", yl_boundary_type = "reflect",yr_boundary_type = "reflect", We can use the run parameter "ed_ignoreBoundaryCondition_n" to make the laser ignore boundary conditions, but I added the code "ed_ignoreBoundaryCondition_1=.true." in the.par file, and it didn't take effect. The laser still does not enter the calculation area through the boundary.
