Joins two face selections with bonded contact, so load passes between their domains through a spring of the contact stiffness. For a rigid joint use Tie. Only Bonded is solved; No Separation is refused.
Faces on the first (independent) side.
Faces on the second (dependent) side, joined to faces A near them.
Search distance in mm (default 1). Points of faces B farther than this from the driver faces stay unconnected.
Bonded: the faces stay together in every direction. No Separation (faces may slide but not open) is not solved yet and is refused.
Optional spring stiffness per unit area (N/mm³), a positive constant. Unset: derived from the two materials (mean of each elasticity matrix's diagonal, averaged over both sides).
