Same behavior as interface TYPE7 with possible switch to Lagrange multiplier formulation; if minimum constant time step (defined with /DT/INTER/CST) is reached.

Description

Automatic Penalty Lagrange

Slide / Void

LAGDT/TYPE7

Solid contact impact at all speeds

Same behavior as TYPE7 with constant minimum time step.

Comments

1.When formulation switches to Lagrange multiplier, the same limitations apply:
•Lagrange multiplier interfaces are compatible with all Lagrange multiplier kinematic conditions.
•Lagrange multiplier interfaces are not compatible with other kinematic conditions.
•Lagrange multiplier interfaces are not compatible with SPMD parallel version.
