[FLASH-USERS] Disable particles

[John ZuHone]

Hi Po-Yu,

Silly question, but in the flash.par, you set

useParticles = .false.

not 

useParticles=F 

correct?

Best,

John

In the list of RuntimeParameters in the log file, I also have useparticles=F. So, I believe I don't have the particles unit in the simulations. It works fine when I have less than two laser beams. However, when I added more beams, the simulation stopped and gave an error:
