Hello.
Seems, if a mesh face size is < a particle diameter then interaction between them is wrong.
Is there a advisable ratio between them?
ps/
I attach my test case for this problem.
Here you can download my results for the case:

Ok, that was a force scaling
Ok, that was a force scaling I introduced in 1.2.7 for small face sizes (see fix_wall_gran.cpp:913).
Probably not a good idea if faces get as small as in your case and the face is planar... Thanks for posting this.
I will remove the scaling in the next release and think about if there is a more clever way to resolve this.
Cheers, Christoph
