Rigid Body Motion Property

Rigid Body Motion property is a physical property assigned to a connection.

Rigid Body motion behavior.

The input and output characteristics are:

  • Input:
    • Degrees of freedom: relaxation of some relations (optional)
    • Local Axis (optional)
  • Output:
    • Point force vector
    • Point moment vector

The output characteristics can be expressed at the given positions in the element and in different axis system:
