Jan Stránský proposed the following answer:
> I was wondering setting cn = cs = 0 in "ViscElMat" gives me the same
result as "FrictMat" as the density of specimen has not changed (because
of the specimen which is the same as when I used "FrictMat") and I
should get the same behavior.

why you "should get the same behavior", if you use different material, different Ip2 and different Law2?
And if you think / are sure that with certain parameters it leads to the same physics, why to change it?

> more than 3 weeks ... less than 15 minutes

I would check your stop conditions and which phase is "freezing" the
simulation..

cheers
Jan
