/INTER/LAGMUL/TYPE2 - Lagrange Multiplier Interface Type 2

Description

Describes the Lagrange multiplier interface TYPE2. If the Lagrange multiplier formulation is used:

•The incompatibility with standard kinematic conditions are checked out automatically in Starter
•Other Lagrange multiplier conditions may be applied to master and slave nodes, unless there is a physical incompatibility
•There is no added mass on master node
•Kinematic conditions are applied to slave and master nodes
