[FLASH-USERS] Proton Imaging on existing checkpoint files

[Wang]

Hi all,

Recently I am using FLASH to simulate proton images. I have already run a simulation and generated a 3D check point file. And I tended to use proton imaging unit and let a proton beam pass through the simulation region of the check point files. If everything’s ok, I can obtain a txt file which records proton’s position.

But now, I can only obtain an empty file, I don’t know how to fix it. 
Thank you for your help, and any suggestions would be greatly appreciated.

This is the setup of protonimaging:
./setup ProtonImaging -auto -3d -geometry=cartesian -parfile=flash.par -nxb=32 -nyb=32 -nzb=32 +protonImaging --without-unit=physics/Hydro --without-unit=physics/Eos -objdir=astrowjz/protonimaging pi_maxBeams=1 pi_maxDetectors=1 threadProtonTrace=True


Best,
Wang
