*beamsectioncreatesolid
Creates a solid beam section for HyperBeam.

Type

Description
Creates a solid beam section for HyperBeam, using a planar collection of elements, lines or surfaces.
If surfaces are used, HyperMesh meshes the surface with quads and trias of the specified order (2nd order recommended), with the meshing parameters such as element size calculated in such a way as to produce elements useful to HyperBeam.
If lines are used, HyperMesh builds a surface through the projected lines and meshes the surface with quads and trias as above.
If elements are used, they must form a single, connected patch with small enough elements that there is at least one internal node providing flexibility for each of the thinnest portions of the beam cross-section.
The base_node and vector_id are used to orient the beam cross-section calculations. HyperMesh beam cross-sections are, by convention, assumed to be in the y-z plane. The centroid and moments of inertia will be reported in those coordinates.
Inputs
- entity_type
- The type of entity to use to create the section. Valid values are elements, lines, or surfaces.
- mark_id
- The ID of the mark containing the entities. Valid values are 1 and 2.
- plane_id
- The ID of the plane to use, defined using the *createplane command. Currently always 1.
- vector_id
- The ID of the y-axis vector to use, defined using the *createvector command. Currently always 1.
- use_plane
- A flag specifying whether or not the plane is reliable; usually this can be inferred automatically from the command.
- base_node
- The ID of the node specifying the origin of all beam section calculations.
- elem_order
- The order (1 or 2) of the elements to use.
