Re: [Question #707043]: Does 'JCFpmPhys' have 'matchmaker'?

Status: Open => Answered
Jérôme Duriez proposed the following answer:
Hi,
*Phys classes never (I think..) have MatchMaker instances in their
attributes, they have actual interaction properties values, after
computations by Ip2_*Phys. Maybe the corresponding doc, about
Ip2_JCFpmMat_JCFpmMat_JCFpmPhys, is indeed imperfect regarding the
mixture rule necessary for your case.
Source code (e.g., [*]) tells us the minimum Material value takes it
all, and there will be no tensile strength between mat1- and
mat2-material particles.
