Trarot | Codes for translation and rotation.
(6 Booleans) Example: 101 111 means the x and z translations, as well as all rotations are fixed; the y translation is free. |

Comments
- The grnd_ID input is obligatory. The boundary conditions will be applied only on nodes that belong to a node group.
- Input format details for the field Trarot are shown above. The six individual codes (one per direction) must be right justified in the ten character fields used by the variable Trarot.
