Comments
- The identifier must be unique in each element family, but it is advised for each element type to have a unique element identifier in the global model.
- More than one truss block may be used to define a part.
- Any number of trusses may be defined in one block.
- If a truss element is used with /MAT/LAW2 (PLAS_JOHNS), the strain rate dependency is not available.
