Altair HyperMesh

New Features

Beam Meshing Tools
Stiffener Mesh
  • Mesh stiffeners are attached to shell elements. Support for Beam (188&189) and Rod (Link180).
    • Support mesh by proximity using free line but seeding nodes on the closest shells.
    • Inherit orientation from the shell normal.
    • Auto offset beams on top of the shell mesh.
    • You can generate a stiffener on each edge of the source shell elements.
  • The tool auto-generates the property SECTYPE and the associated section (BEAM card) from the given beam section.
    • You can leverage metadata beam section on parts holding free lines. These metadata are automatically created when importing Aveva Marine or OCX CAD formats.
Member Mesh
  • Mesh lines/edges/node path with either Beam, Rod, or Pipe engineering configurations.
  • Element type/section and property are created accordingly.
  • Beam section types are filtered based on the desired configuration.
    • for LINK180, the beam section area is directly mapped to the to field area of the section entity.

Beam Edit Tools
The Align tool is used to adjust elements' n1→n2 order.
  • Reorder nodes so the X-axis follows the closest global or local system axis in ascending order.
  • The tool supports all types of beam elements.
Orient
  • Support beams with a section entity with a beam section assigned.
  • Reorient the normal to shell on both sides.
  • You can rotate elements along their local X-axis by a given angle.
  • With the vector tool, select arbitrary orientation.
    • A node is created from that vector and used as the third node of elements.
  • Directly pick a third node or pick a reference beam element to propagate the same orientation as the reference element.
    • A node is created per element such that n1→n3 follows the same vector.
Offset
  • Offset beams on the shell mesh.
  • Assign offset keys: CENTROID/SHEAR CENTER/ORIGIN.
  • Apply the same offset as a reference element.
  • Apply incremental offset with a manipulator or set directly offset components.

Inflate
Convert Beams to Surface and Shell Mesh
  • Beam188 with either standard beam section or shell beam section.
  • The tool creates surfaces from the beam section midline.
  • Generate 2D mesh (SHELL181) with thickness assigned.
Convert Beams to Solids
  • Beam188 with a standard beam section only.
  • Generate solid geometry from beams.

Enhancements

  • Mapping real constants of the COMBIN39p property to a curve entity has been added.
