How do you plot this?

Dear Andreas

I've include the modification at the Field Solver, and now the error doesn't
occur. But the tracking of the particles are absolutely unexpected. I attach
two plots of the orbits with 1000 and 999 particles. You could see that the
results are complete different.

Best regards

Hi Pedro, try to change:

FSTYPE=FFT, MX=32, MY=32, MT=64


FSTYPE=FFT, MX=16, MY=16, MT=32, ….

You only have 1000 particles and apps. 65k grid cells.

How many cores do you use?

Dear Andreas.

I'm using the version 1.4.0 of OPAL.
I share with you the input files in a dropbox folder.

Hi Pedro

can you make all the input files available so we can reproduce the problem.
Which version of OPAL are you using?
Cheers Andreas

Dear OPAL users, I write you because we have some problems about the
simulation of a big number of particles.
We simulate without problems our machine with the correct electric and
magnetic fields, including the geometry in the simulation. But when we
increase the number of particles above 1000, we obtain the following error in
the output:

Error> Interpolator::getFieldIter: attempt to access non-local
on node 0
Error> Dumping local owned and allocated domains:
Error> 0: owned = {[0:31:1],[0:31:1],[0:31:1]}, allocated =
Error> Error occurred for BareField with layout = Domain =
Error> FieldLayoutUsers = 3
Error> Total number of vnodes = 1
Error> Local Vnodes = 1
Error> vnode 0: Node = 0 ; vnode_m = -1 ; Domain =
Error> Remote Vnodes = 0
Error> Calling abort ...

This error don't occur when the number of particles is lower than 1000.
We have tried to solve this error changing the fieldsolver in the code for a
1000 particles, but the results are completly diferent if we compare with the
simulation with a number of particles of 999. I

I will appreciate any suggestion to solve this problem.

Pedro Calvo
