/INTER/LAGMUL/TYPE2
Block Format Keyword Describes the Lagrange multiplier interface TYPE2.
Description
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 main and secondary nodes, unless there is a physical incompatibility
- There is no added mass on main node
- Kinematic conditions are applied to secondary and main nodes
