[FLASH-USERS] HOW BDRY WORKS IN FLASH

[史路林]

Dear Flash users,




In the process of running the study, the problem of free expansion of the solid target boundary is encountered. After previous adjustments, BDRY=1 (solids) and BDRY=-1.0 (fluids) were used to distinguish between solids and fluids.
It was found that during the operation, the laser energy could not be deposited well, and the laser beam was completely reflected.
So I want to know how this BDRY works? and whether there are other ways to distinguish between fluid and solid interfaces, such as adjusting the degree of ionization.
The program I modified is in the attachment part, and the main changes are: 

1. Added to the Simulation_adjustEvolution.F90 file: 

                  if (blkPtr(TARG_SPEC,i,j,k) > 933(aluminum)) then 

                  blkPtr(BDRY_VAR,i,j,k) = -1.0
                  end if
                  if (blkPtr(TARG_SPEC,i,j,k) < 933) then
                   blkPtr(BDRY_VAR,i,j,k) = 1.0

2. Added to the Simulation_initBlock.F90 file:

          #ifdef BDRY_VAR 

           call Grid_putPointData(blockId, CENTER, BDRY_VAR, EXTERIOR, axis, bdry)




If you've had this problem before, or know how to fix it, please get back to me, thank you!
Best regards,
