Question #216910 on Yade changed:
https://answers.launchpad.net/yade/+question/216910

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello Zhaochen,

see the documentation [1], Law2_ScGeom_ViscoFrictPhys_CundallStrack has
parameters "viscosity" and "creepStiffness". According to the names of
these parameters, they have something to do with time dependent part of
material law and thus damping.

cheers
Jan
