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.
- Meshing Preferences
  Define meshing preferences.
- Element Configurations
  Each element has an associated element configuration. An element configuration tells HyperMesh how to draw, store, and work with the element.
- Supported Solver Cards
  Solver cards supported for elements.
- Review Element Quality
  Use the Element Quality view to review element quality while simultaneously editing your model.
- 1D
  Explore the different types of 1D mesh you can create in HyperMesh.
- 2D
  Explore the different types of 2D mesh you can create in HyperMesh.
- 3D
  Explore the different types of 3D mesh you can create in HyperMesh.
  - 3D Elements
    Supported 3D elements.
  - Create 3D Mesh
    Explore the tools used to create 3D mesh.
  - Solid Mesh
    Explore the tools used to create solid mesh.
    - Tet Meshing
      Use the Tet tool to fill an enclosed volume with first order or second order tetrahedral elements.
      - Create Tet Mesh
        Use the Tet: Create tool to create tetra mesh from closed volumes of shell elements, or from solid or closed surface geometry.
      - Remesh Tet Mesh
        Use the Tet: Remesh tool to regenerate the mesh for a single volume of tetrahedral elements.
    - Map Meshing
      Use the Map tool to create and edit a mesh of solid elements in a solid geometric volume.
    - Create Thin Solid Mesh
      Use the Thin Solids tool to create 3D mesh on thin solids. The mesh is created by first generating a 2D mesh on a selected set of source faces, and then extruding this mesh to generate solid hexa or wedge elements.
    - Acoustic Cavity Meshing for Interior Noise
      Acoustic cavity meshing for interior noise generates a fluid volume mesh used to calculate the acoustic modes (or standing waves) inside the air spaces of a vehicle or similarly enclosed structural model.
    - Acoustic Cavity Meshing for Exterior Noise
      Acoustic cavity meshing for exterior noise generates a fluid volume mesh and boundary mesh used to calculate the acoustic modes, or standing waves, in the external air spaces of a powertrain, e-motor or similarly enclosed structural model.
  - Edit 3D Mesh
    Explore the tools used to edit 3D mesh.

Remesh Tet Mesh

Use the Tet: Remesh tool to regenerate the mesh for a single volume of tetrahedral elements.

From the 3D ribbon, click the Tet > Remesh tool.

Figure 1.
Optional: On the guide bar, click to define tetra mesh options.
Select elements.
Optional: Activate the Baffles selector on the guide bar and select baffle shells.
Optional: Activate the Anchors selector on the guide bar and select anchor nodes.
Click Mesh.

Figure 2.

Advanced Options

The following options are available in the guide bar options menu ().

Fix mid-nodes for second order mesh

In case of 2nd order tetras, this option fixes the mid edge node of surface mesh while volume meshing.

Surface mesh treatment

This option affects those faces of tetra elements which are on the outside of the volume, meaning the tetra faces which have only one tetra attached. Those faces are called free boundary faces.

Retain existing: Retain existing free boundary faces.
Remesh: Remesh the free boundary faces.
Swap: Swap the edges of the free boundary faces. The mesh nodes stay unchanged.

Mesh destination

The component in which the tetra mesh is organized.

Restrict minimum size

None: Will not enforce any size.
Size: Will enforce minimum tetra edge length.
Height: Will enforce minimum tetra height (shortest distance from tetnode to opposing tetra face.)
