Comments

  1. If node_ID1 and node_ID2 are defined, the rotation will be done around the vector defined by node_ID1 and node_ID2. The center of rotation will be the node_ID1. If only one node is defined, the error message is displayed.

    Figure 1.

    Otherwise, the rotation will be done around the vector defined by point_1 and point_2. The center of rotation will be the point_1.

  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 cannot 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.
