Manage Files and Data
Create, open, import, and save models.
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.
Meshing and Elements
Explore the different types of mesh you can create in HyperMesh and create and edit 0D, 1D, 2D, and 3D elements.
Model Build and Assembly
Create, organize and manage parts and subsystems.
Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
