Kinematic Constraints

Kinematic constraints are boundary conditions that are placed on nodal velocities. They are mutually exclusive for each degree of freedom (DOF), and there can only be one constraint per DOF.

There are seven different types of kinematic constraints that can be applied to a model in Radioss:
  1. Rigid Body
  2. Initial static equilibrium
  3. Boundary Condition
  4. Tied Interface (TYPE2)
  5. Rigid Wall
  6. Rigid Link
  7. Cylindrical Joint

Two kinematic conditions applied to the same node may be incompatible.
