Automatic Penalty Lagrange

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

Table 1. Interface Type with Automatic Penalty Lagrange
Contact Treatment   Types Application Description
Automatic Penalty Lagrange Slide / Void /INTER/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.
