What's New
View new features for HyperMesh CFD 2024.1.
Get Started
Learn the basics and discover the workspace.
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.
- Sketching
  Create and edit 2D parametric sketch geometry.
- Geometry
  Create, edit, and cleanup geometry.
- Discrete Geometry
  Work with discrete geometry like FE Geometry and floating elements.
- Model Build and Assembly
  Create, organize and manage parts and subsystems.
  - Part Browser
    Use the Part Browser to create, organize and manage the CAE part structure/hierarchy.
  - Mechanism Browser
    Create and articulate a kinematic mechanism based on FE mesh using the Mechanism Browser.
  - Organize Assemblies, Parts, and Bodies
    Use the Part Browser and the right-click menu options to organize your model into a hierarchy of assemblies, parts, and bodies.
  - Bulk Import
    Use the Bulk tool to load all CAD files in one go, sanitize names, remove small bodies, split parts per body, and save a representation for each part.
  - Part Controls
    When you have large CAD models, such as a full vehicle model - it can be difficult to bring the entire model into the session. Use the Part Controls tool to shatter CAD files for each part, allowing you to mesh those parts in batch without bringing them into the session.
  - Load and Save Part Representations
    Use the Representation tool to load and save representations for selected parts. This is useful for storing and retrieving data as required.
  - Group Entities
    Collect entities, such as parts and surfaces.
  - Find Duplicates
    Use the Duplicates tool to locate tiny and duplicate parts in b-spline CAD models.
  - Merge and Split Parts
    Use the Merge/Split tool to merge parts or split them by connectivity or by face.
  - Find and Isolate Specific Geometry Types
    When performing cleanup or defining simulation parameters, it can be helpful to first find and isolate certain types of geometry. This will give you a better idea of the areas in the model you need to focus on.
  - Classify Parts
    Set up and use machine learning (ML) models to automatically classify parts under user-defined labels and into part sets.
  - View Entity Count
    View the number of entities present in the current model.
  - Assign Metadata
    Assign metadata values to selected entities. Once assigned, metadata can be used in advanced selection.
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.

Load and Save Part Representations

Use the Representation tool to load and save representations for selected parts. This is useful for storing and retrieving data as required.

From the Assembly ribbon, click the Representation tool.

Figure 1.
Select parts.
For faster speed, select the root part. To do this, click on the guide bar to open advanced selection, then pick an assembly By ID.
Tip: You can see the ID of a root part in the Part Browser.
Click on the guide bar to choose whether to load, save, or unload the associated representation.
