different figures for Bx on separate systems

[rezaplasma]

Hi
I run example of FBPIC script (lwfa_script) on local computer and computational server so that I got different figures for Bx in first iteration

on server:


on local computer:

what's the problem?
thanks

@rezaplasma the problem is definitely with the computational server case.
To debug this, one would need to know how FBPIC was installed on the server, and check if there were no warnings, errors in the output of this simulation.
Judging by the ranges of you z-axis, the zmin and zmax values are different for these cases, (-10,30) and (-30,30) , and the problematic simulation has a longer box. Are there any other differences between these cases?

Hi @hightower8083

thanks for your reply and sorry for my late reply
yes, they are different cases chosen for two simulations but they do not affect the problem

I have installed FBPIC with conda package and then run pip install fbpic statement as mentioned in document of installation!
should I use another way to install fbpic on computational server?
and does this problem generally affect the final results of simulation?

Thanks
