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 index{[-2147483648:-2147483648:1],[-2147483648:-2147483648:1],[-2147483648:-2147483648:1]} on node 0

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.
