bscpp = block.subcontact.partner(bscp)

When face-vertex subcontacts are created, two subcontacts generally exist at the same location: vertex of block 1 contacting face of block 2, and face of block 1 contacting vertex of block 2. This function returns the “partner” subcontact that exists at the same location as the input subcontact. Note that in large strain after some cycling, subcontacts may no longer be at the same location, in which case this function may return a null pointer.


bscpp - block subcontact pointer to partner


bscp - block subcontact pointer
