Sessions and Report Templates
Set up sessions and create report templates.
Interface with External Products
Solver interfaces supported in HyperMesh.
Entities and Solver Interfaces
A solver interface is made up of a template and a FE-input reader.
Browsers
Browsers provide a structured view of model data, which you can use to review, modify, create, and manage the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting, which enhance your ability to navigate and interact with the model data.
Sketching
Create and edit 2D parametric sketch geometry.
Topology
Create, edit, and cleanup geometry.
FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.

Materials

Material definition.

Composite laminates are typically made up of layers of isotropic, orthotropic and/or anisotropic materials. Specific material definitions vary by solver. For example, in OptiStruct:

Linear isotropic material for shell and solid elements: MAT1
Linear orthotropic material for shell elements: MAT8
Linear orthotropic material for shell and solid elements: MAT9OR
Linear anisotropic material for solid elements: MAT9
Nonlinear isotropic/orthotropic/anisotropic material: See Multiscale Designer

Materials can be created from the Model Browser, the Model ribbon, or the Composite Browser. Specific solver cards and attributes can be set in the Entity Editor.

The following table displays a list of typical composite material properties.
