    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

> Could you have any advice to me how to get the data

something like this?
###
with open(outFile,'w') as f:
   for i in O.interactions:
      n = i.geom.normal
      pd = i.geom.penetrationDepth
      fn = i.phys.normalForce.norm()
      f.write('{} {} {} {} {}\n'.format(nx,ny,nz,pf,fn))
###

for plotting, gnuplot with polar plotting can be used [1]. For more
info, please provide more information about what you want to achive and
what "specific interaction direction data", ideally with a MWE of a
complete simulation up to just before to be saved and postprocessed.

cheers
Jan
