<div>Hi Petros,<br>
Thank you.<br>
I will try to increase my ed_maxRayCount runtime parameter. But
how about pt_maxPerProc? I set it in flash.par and found it is
listed under "Ignored Parameters". I believe it is because I don't
have the unit (particle unit?). Do I need to include that? or do I
just increase my ed_maxRayCount and ignore pt_maxPerProc?<br>

<div>Hi Po-Yu, <br>
<br>
</div>
the error message you are having is misleading. <br>
<br>
As Norbert mentioned, the particles used by the laser unit
are a different beast altogether but share some of the
infrastructure. To allow for more rays you need to increase
your ed_maxRayCount runtime parameter in the flash.par,
making sure that the total number of rays you are launching
does not exceed this number. <br>
<br>
</div>
<div>I'll update the error message to reflect this. <br>

The +laser setup uses -without-unit=Particles, which means
that the Particles unit is dissabled. What the laser uses is
the Grid/GridParticles<br>
routines to 'handle' particles. The rays from the laser are
treated<br>
as particles when moving them through the grid. So the
particles unit is<br>
different from the actual tools (sitting in the Grid unit)
that are used to move the particles (in your case the rays)
through the grid.<br>
<br>

Hi John,<br>
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.<br>
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<br>

Hi Po-Yu,<br>
<br>
Silly question, but in the flash.par, you set<br>
<br>
useParticles = .false.<br>
<br>
not<br>
<br>
useParticles=F<br>
<br>
correct?<br>

Hi all,<br>
I am doing simulation for imploding cylindrical
target using lasers. I am using the hydrodynamics
units and don't use the particles unit. 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:<br>
<br>
Overflow! Mesh PE 9 , gettingFrom
2 , recvCount 8068 , max particles 10000<br>
DRIVER_ABORT: [gr_ptMove]: Insufficient space in
particles communication buffer: increase
pt_maxPerProc<br>
<br>
So, my questions are:<br>
<br>
(1) I thought the particle unit was not used. Why
did it consider the number of max particles.<br>
(2) If I have to have the particle unit, when can
I increase pt_maxPerProc ? in the flash.par? or as
setup variable?<br>
<br>
Thank you,<br>
