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.
- Manage Parts
  - Part Browser
    Use the Part Browser to create, organize and manage the CAE part structure/hierarchy.
  - About Parts, Part Assemblies, Part Instances
    A part is an engineering representation of a physical part, and a part assembly is a group of part assemblies and/or parts. Part Instances, which are recognized from PDM, are automatically converted to Part Instances on import into HyperMesh.
  - Create Parts, Part Assemblies, and Part Instances
    Only CAE parts and part assemblies can be manually created in HyperMesh. PDM parts and part assemblies must be imported into HyperMesh.
  - Import Parts, Part Assemblies, and Part Instances
  - Organize Part Assemblies and Parts
    Organize part assemblies, parts, and components in your model.
  - Transform Parts Assemblies and Parts
    Translate, rotate, reflect, scale, and position selected parts and part assemblies.
  - Save Assemblies as HyperMesh Binary Files
    The part assembly can be saved as a self-contained binary file, which will include the part assembly based hierarchy and attributes such as components, properties, and materials.
  - Manage Representations
    - About Representations
      Different methods for modeling a part are called representations.
    - Create Representations

      Part representations can be added from external sources such as solver decks and HyperMesh binary files or from the Part Library.
    - Browse Library Content
      Review library content using the Library Viewer.
    - Load Representations
      Part representations can be loaded from your current HyperMesh session or from the Part Library.
    - Reload Representations
      Restore part representations to their original state.
    - Unload Representations
      Unload part representations from a session.
    - Update Metadata From PDM
    - Sync Metadata To PDM
      Sync PDM metadata (PDM PID, PDM Thickness, PDM Material, and PDM MID) based on a selected part or part's metadata (PID, Thickness, Material, MID).
    - Save Representations
      After importing a BOM and creating respective representations, you can save the representations locally or in the Part Library.
    - Delete Representations
      Part representations can be deleted from the current HyperMesh session and from the Part Library.

      Settings to configure the representation entity management behavior.
  - Manage Part Revisions
    Manage, control and update Major, Study and Library Part revisions using the Part Library.
  - Manage Configurations
    Group common and unique parts/part assemblies together in part sets, and organize parts and part sets that are unique to a configuration.
  - PDM Live Connection
    Using PDM live connection, on-demand downloading of datasets from external PDM systems such as Teamcenter is possible
  - Map Legacy Solver Decks to Available Part Hierarchy
    Align existing legacy decks, which lack part hierarchy, with an established part hierarchy.
  - Teamcenter - HyperMesh Integration
    All BOM-related information, including part/assembly hierarchy, part attributes, and representation information is organized and displayed in the Part Browser.
- Manage Subsystems
- PostgreSQL Installation and Configuration
  Also referred to as Postgres, PostgreSQL is an object-relational database management system with emphasis on extensibility and standards compliance.
