3.11.1.1 Fix Rigid Constraint

The fix rigid constraint fixes one or multiple rigid degrees of freedom. It requires the following parameters.
parameters Description
rb The rigid body's material ID (1)
dofs The list of rigid degrees of freedom to fix. (2)
Comments:
  1. This is the “id” attribute assigned to the corresponding rigid body material as defined in the Material section.
  2. The values allowed for the dofs parameter are: Rx, Ry, Rz, Ru, Rv, Rw. The first three (Rx, Ry, Rz) represent the displacement degrees of freedom. The other three (Ru, Rv, Rw) are the rotational degrees of freedom.
The following example fixes the displacement degrees of freedom.
<rigid_constraint type="fix">
  <rb>1</rb>
  <dofs>Rx,Ry,Rz</dofs>
</rigid_constraint>
