Karol Brzezinski proposed the following answer:
Hi Leonard,
DMT stands (most likely) for the Derjaguin-Muller-Toporov model. I think that
you mistook interaction physics class [1] for its functor [2]. You need to pass
gamma (Surface energy parameter [J/m^2] ) to Ip2_FrictMat_FrictMat_MindlinPhys,
and it will compute adhesion force for distinct interactions separately. Of
course you neet to set includeAdhesion=True in the constitutive law too (as you
did).
I believe that the code for Hertz-Mindlin contact model is here [3]
