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 triangular shell block can be used to define a part.
- Any number of triangular shells can be defined in one block.
- Using different numbers for 3-node and 4-node shells is recommended.
- For Coordinate system in 3-node shell element, refer to Radioss Coordinate System in the User Guide.
- If def_orth = 1, the
orthotropy angle,
is only used in /PLY and /PROP/TYPE19 (PLY).
