Thank you for your help!
I have done something, still not perfect, but starts to work ;-)

Spheres are behaving erratically now, because the acting forces are
not radial, but orthogonal. I will fix that soon also.
I will commit that as soon
Hi,

apparatus TRITRI in lab. 3S-R. Experimentally they found that the shear
1) was it done already by someone, and I missed this?
Membranes have been fully implemented for a while, as minkowsky sums of
triangulated surface and sphere, in... SDEC!
The most complex part to implement in Yade is you have to track when
interactions are going from body-facet1 to

To detect spheres that touch the membrane I will do a Delaunay
triangulation of whole sample, with extra four points added.
This is already implemented in Yade, with weighted radical Delaunay.
