Comments

  1. If node_ID1 and node_ID2 are defined, the translation will be performed with the vector (node_ID1, node_ID2). If only one node is defined, an error message is displayed.

    Otherwise, the translation will be done with the defined value X_translation, Y_translation and Z_translation.

  2. A transformation can not apply to a node group and a submodel at the same time.
  3. If the transformation is done on a submodel, all the options of this submodel are transformed.
  4. A node can not be transformed both in a submodel and a node group.
  5. Transforms applied to node groups via grnd_ID only transform the nodal coordinates. Material directions for orthotropic materials and boundary conditions such as initial velocity, imposed movement are not transformed. To provide a complete transformation, the /TRANSFORM card should reference a //SUBMODEL and not a node group.
