Hi All,

As you may know the "iAdhesion" is computed from the minima of "iCohesion".

However I need to change this logic, I was told  "MatchMaker" in Ip2_CohFrictMat_CohFrictMat_CohFrictPhys should do what I am looking for. I have tried below engine, however it does not work.

O.engines=[
        ForceResetter(),
        InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb(),Bo1_Facet_Aabb(),Bo1_Wall_Aabb()]),
        InteractionLoop(
                [Ig2_Sphere_Sphere_ScGeom6D(),Ig2_Box_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom()],[Ip2_FrictMat_FrictMat_FrictPhys()],
                [Ip2_FrictMat_FrictMat_MindlinPhys(en=MatchMaker(matches=((mat1,mat2,.6),(mat2,mat2,.9))),es=MatchMaker(matches=((mat1,mat2,.6),(mat2,mat2,.9))),krot=3)],   
                [Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(normalCohesion=MatchMaker(matches=((mat1,mat2,500),(mat2,mat2,1e6))),shearCohesion=MatchMaker(matches=((mat1,mat2,50e6),(mat2,mat2,80e6))),label="cohesiveIp")], [Law2_ScGeom_MindlinPhys_Mindlin(includeMoment=True,includeAdhesion=True)],
                [Law2_ScGeom_FrictPhys_CundallStrack(),Law2_ScGeom6D_CohFrictPhys_CohesionMoment(
			useIncrementalForm=True, #useIncrementalForm is turned on as we want plasticity on the contact moments
			always_use_moment_law=False,  #if we want "rolling" friction even if the contact is not cohesive (or cohesion is broken), we will have to turn this true somewhere
			label='cohesiveLaw')]

Would you please advise?

Thanks 

Seti
