Welcome
What's New
View new features for HyperMesh CFD 2025.
Get Started
Learn the basics and discover the workspace.
- Platform Support
  Platforms, operating systems, and processors supported by Altair HyperWorks 2025 products, which includes 2025 solver packages.
- User Interface
  Explore the user interface.
- Adjust the View
  View controls enable you to control the view and display of your model in the modeling window.
- Selection
  Select and deselect entities to modify with other tools. Selected entities are outlined to indicate their selection state.
  - Entity Selectors
    Use entity selectors to specify which type of entity you are able to select.
  - Select Entities
  - Append and Remove Entities From a Selection
  - Graphical Selection (Idle Mode)
  - Perform Extended Entity Selection
    Use extended entity selection to find, filter, and select subsets of entities. You can also save and retrieve previous selections.
  - Quick Advanced Selection
    Use quick advanced selection to associate a preferred advanced selection method to different entity types. The advanced method becomes instantly accessible while holding the Alt key during any selection action.
  - Keyboard Shortcuts & Mouse Controls
- Measures
  Learn about the different types of measurements available for each setup environment.
- Snaps
  Use snap points to help align geometry.
- Move
  Translate, rotate, and align the model.
- Define Orientation
  Several tools require you to define a plane or a vector direction to perform a certain function, such as dragging geometry along a vector, spinning it about an axis, or splitting it with a plane. The Plane and Vector tools are used to define and edit planes and directions.
- Edit and Delete Parameters Using the Legend
  Use the legends to visualize, edit, and delete instances of model setup parameters.
- Enter Data Using the Table and Plot Area
  Use the table and the plot area together to create, edit, and visualize input points for varying data sets.
- Undo-Redo
  Undo and redo actions.
- Keyboard Shortcuts and Mouse Controls
  Default keyboard shortcuts and mouse controls.
Onboarding Resources
Discover HyperMesh CFD functionality with interactive tutorials and community resources.
Solution Layers
Solution-centric workflows allow you to traverse through modeling environments using a dedicated UI layer.
Manage Files and Data
Create, open, import, and save models.
Convert
Use the Convert tool to convert entire models between data types.
Geometry Modeling
Manage CAD, FE, and 2D parametric sketch geometry.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help
More resources for AcuSolve and ultraFluidX solvers.
