Status: Open => Answered
Anton Gladky proposed the following answer:
Hi,
for example, in ViscoelasticPM the damping coefficient is calculated
for the interaction like [1]:
phys->cn = (cn1?1/cn1:0) + (cn2?1/cn2:0); phys->cn =
phys->cn?1/phys->cn:0;
it depends on the contact law, what you are going to use.
