Question #294932 on Yade changed:
https://answers.launchpad.net/yade/+question/294932

    Status: Open => Answered

velimier proposed the following answer:
1st: you should increase the young values and that will solve the problem with passing grains.
2nd: you may import the ground as surface and present it as facets. It is something like this:

surf=gts.read(open('yourSurf.gts'))
O.bodies.append(pack.gtsSurface2Facets(surf,wire=True)) [see gts-horse example]

if you are using CAD to draw the ground you can export that surface to
the .gts format directly (depends on software, Rhinoceros has that
option), or you can export the surface to .stl format and convert it to
.gts using stl2gts tool.

Hope it helps,
Veljko
