/TRIA
Block Format Keyword Describes the 2D solid elements based on 3 nodes. TRIA elements must be defined in the global YZ plane.
This element is only used with /MAT/LAW151 (MULTIFLUID) and /PROP/TYPE14 (SOLID). It is not compatible with any failure model.

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 tria block can be used to define a part.
- Any number of trias can be defined in one block.
- The TRIA elements must be defined in the global YZ plane with the element normal pointing in global X direction.
- N2D3D parameter in /ANALY enables axisymmetrical modeling (N2D3D=1) or plane strain modeling (N2D3D=2).
- Use /H3D/ELEM for h3d output of TRIA element.
