jyvikoandClaude Opus 5.5 85f0905db1 solver: single-surface (self) contact in nonlinear static steps ...

General contact, on a set's faces or every exterior face of the solids, is mortar contact
with one face list as both sides: each face against every other one that faces it, shares no
node with its element and is not reached through more than half an element, paired both
ways. Tested by a nearly incompressible Mooney-Rivlin C-ring (hybrid hex8) closing on itself
(no penetration beyond the mortar's weak enforcement, mirror symmetry to 1e-6) and, heavy, a
rubber bellows whose folds press on each other.
