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:
