[FLASH-USERS] Disable particles

[pchang]

Hi John,
Yes. That's what I did also. More precisely, I tried two ways: (1)have 
useParticles = .false.  in flash.par (2) have setup variable +laser 
which automatically set -without-unit=Particles.
I think in the log file, it shows "useParticles=F" just to show the run 
time setting. So I believe the particle unit has been disable. And 
that's why it doesn't make sense to me when I have an error about 
particle number when I don't have the unit

Best,

Po-Yu

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:
