Chareyre proposed the following answer: Hi Ricardo, It will work if GSTS can find relevant values for kn, ks, cn and cs. An approach is to keep them updated to reflect the tangent values of stiffness/viscosity: dF/du and dF/dv (u: disp., v: velocity). For instance, if your law reads: fn = E*un^2, you would define phys->kn=2*E*un so that GSTS can use it. I can see a regression in HertzMindlin on this aspect since, some time ago, it was defining kn and ks in this way for the sole purpose of getting results in GSTS. Currently they are not defined (hence kn=ks=0).
