What's New
View new features for Altair HyperWorks 2024.1.
Get Started
Learn the basics and discover the workspace.
Tutorials
Learn more about the Altair HyperWorks suite of products with interactive tutorials.
Startup Procedures and Customizations
Start and configure the applications.
Tool Finder
View a list of deprecated panels and their newer, equivalent workflows.
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.
- 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.
  - Setup 1D Mesh
  - Beam Mesh
  - 0D/1D
    Models that require 0D and 1D elements can be created through controllers.
  - Line Mesh
    - Edit Density, Size, or Chordal Deviation
      Edit density, size, or Chordal deviation along lines.
    - Edit Mesh Biasing and Element Size Distribution
      Apply linear, exponential, or bellcurve biasing to individual edges of a surface, and edit the elements size distribution.
    - Element Biasing
      The automeshing process enables you to bias the placement of nodes so that their intervals are not uniform in size.
- 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.

Edit Density, Size, or Chordal Deviation

Edit density, size, or Chordal deviation along lines.

The local edge element size approximation is based on edge density value and length. Hence, it can vary slightly for two edges with the same density value.

From the microdialog, click and select the desired method.
Left-click to select the edge(s) to modify.
Edit element density or size in the following ways:
- Increase individual edge values by holding Ctrl while left-clicking on an edge; decrease individual edge values by holding Ctrl while right-clicking on an edge.
- Scroll edge values by holding Ctrl while scrolling the mouse wheel up and down. Hovering directly over an edge will only modify that edge; hovering over empty space will modify all selected edges.
- Specify an edge value in the microdialog and press Enter. If multiple edges are selected, a common value will be applied. If multiple edges with different edge values are selected, use the arrows in the microdialog to modify individual edge values simultaneously, without applying a common value.

Tip: Clear your selection by left-clicking in empty space.
