/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

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