Question #269315 on Yade changed:
https://answers.launchpad.net/yade/+question/269315

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Behzad,

just to confirm we are discussing the same problem, I'll repeat my two
requests from #3:

please provide also a Python script (even if we can't run it). Do you use
> more particle shapes?


furhtermore, please attach also the .hpp and .cpp files with your
implementation so we can see or compile it and try, the problem might be
also there (e.g. forgotten switch of FUNCTOR2D arguments)

I thought this approach should have worked, sorry it does not. To solve it,
somebody should dive deeply inside the code and find out what is going on
for these combinations of shapes and materials.. I opened a bug [1], but
currently I don't have time capacities to solve it myself..

cheers
Jan
