Comments
- 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.
- The equation of the
hyper-ellopsoid is:
(1) - A hyper-ellipsoid can only be a main surface of /INTER/TYPE14.
