Comments
- Surfaces are used to define interfaces in 3D analysis and pressure loads.
- The node_ID4 may be omitted for triangular elements.
- Segments may be given by "cut and paste" of shell element input data.
- All nodes must belong to a shell element, a brick element or a triangular shell element.
- A surface cannot be defined using Madymo surfaces.
- A surface cannot be defined by associating a hyper-ellipsoid and another type of surface.
