Question #288608 on Yade changed:

    Status: Open => Answered

Anton Gladky proposed the following answer:
Hi,

as a "quick" solution you can try to use clumps and
ViscEl particle model, where contact damping is implemented.
I will probably also need such a function soon in CohFrictMat,
so I will try to implement it in FrictMat. It should be done
wise not to duplicate the code.

Best regards


Anton
