Comments

  1. Three starting and three ending points, define a transformation which allows rotation and translation. The starting and ending points can be defined using nodes or coordinates.


    Figure 1.
  2. If the six node_ID are defined, the transformation is defined using nodes and the coordinate point input is not used. If the node_ID input is blank, the X, Y, Z coordinate point input is used to define the transformation.
  3. Caution, 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.
  4. A transformation cannot apply to a node group and a submodel at the same time.
  5. If the transformation is done on a submodel, all the options of this submodel are transformed.
  6. A node cannot be transformed both in a submodel and a node group.
