Comments

1.	A surface is a set of 3-node or 4-node segments. It can be defined:

•	explicitly, with segment connectivity

•

by box

•	by subsets or parts (all 3-node and 4-node shells belonging to these entities are used to define the surface)

•	by submodels (all 3-node and 4-node shells belonging to parts in the listed submodels are used to define the surface)

•	by properties or materials (all 3-node and 4-node shells belonging to these entities are used to define the surface)

•	by shell groups

•	with other surfaces

2.	All nodes must belong to a shell element, a brick element or a triangular shell element.

3.	A surface cannot be defined using Madymo surfaces.
