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.
- Connector Preferences
  Connector preferences describe how different connector realizations behave when changes are made.
- Connector Browser
  Use the Connector Browser to view and modify connectors in the current model.
- Define Connector Controls
  Use the Control Manager to create and edit the various types of controls that will be used later when realizing connectors.
- Create and Realize Connectors
  Use the tools in the Create tool set to create connectors, assign controls, and realize.
- Auto Point
  Create weld points at a predefined pitch distance so that the model build process can continue without the need to wait for the published weld data from CAD. The Auto Point tool is useful when working with elements, not geometry.
- Auto Fastener
  Use the Auto Fastener tool to identify and pair holes to create fastener connectors between components and parts. The process works on 2D/3D mesh.
- Auto Line
  Use the Auto Line tool to identify locations to create line connectors between components and parts. This process works on 2D geometry and mesh.
- Auto Area
  Use the Auto Area tool to identify locations to create area connectors between components and parts. This process works on mesh.
- Apply Mass
  Create a dummy connector entity to add mass to a part, or create areas of mass to represent parts not present in the CAD or FE data.
- Connector Quality Check
  Use the Quality controller to perform various checks on connectors and realized FE.
- Absorb
  Use the FE Absorb tool to create connectors from existing mesh that meet specific types of realizations.
