https://answers.launchpad.net/yade/+question/688681

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

> I want to directly input Kn and Kt ... instead of using the "young"
parameter.

See [1,2,3] discussing similar topic

> To do so, as the "FrictMat" has not Kn and Kt, I tried to define
material and contact law based on "ViscElMat".

you can use FrictMat, see [1], #3 and #8

> but, the result is different than the "FrictMat" case while the
specimen is the same. ... I am wondering why that happens?

well, obviously, because you are using different model with different
governing equations..

cheers
Jan
