Block Format Keyword This pentahedron element is currently only supported as a thick shell Isolid =15 element and used with /PROP/TYPE20 (TSHELL). For non-thick shell solid 3D pentahedron elements, create a degenerated /BRICK element.

  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. This option defines a pentahedron, which is only available with Isolid =15 (PA6 thick shell element formulation /DEF_SOLID).
