Manage Files and Data
Create, open, import, and save models.
- Supported File Types
  The following file types can be read, depending upon the active application.
- Create New Files
  Create a new file.
- Open Files
  Open a file.
- Import Files
  Import various file types into the selected client.
- Warning Messages When Loading Files
  When loading an .hm file, you may receive a warning message depending on the version and solver interface in which the file was last saved.
- Change Solver Interfaces
  Load a different solver interface in the application.
- Conversion Between Solver Formats
  Convert finite element models to another solver format.
- Load Files
  Load command files, scripts, solver template files, preferences, or the Metadata Table.
- Save Files
  Save all of the data in your current session.
- Collect Diagnostics Information
  The Diagnostics Information Gathering utility collects diagnostics files in the case of a crash and saves them to a common folder.
- Export Files
  Export various file types from the selected client to another format.
- Include Files
  Most FEA solvers allow you to organize the input deck into separate files and provide a mechanism to include (or refer) these files in the main input deck.
- Import Templates
  Templates can be imported by means of the File > Import menu.
- Take a Screen Capture
  Record a video or take a snapshot of the screen.
- Convert Units
  Use the Units tool to convert a finite element model from its initial unit system to a new unit system.
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.
Model Build and Assembly
Create, organize and manage parts and subsystems.
Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Skeleton Modeling
Create a reduced ordered model to facilitate optimization at the concept phase.
Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperMesh.
Design Explorer
Multi-disciplinary design exploration and optimization tools.
Validate
Validate the model built before running solver analysis.
Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.
Crash and Safety
Tools used for crash and safety analysis.
Airbag
Use airbag folder utilities and export a resulting airbag in a Radioss deck.
Aerospace
Essential utility tools developed using HyperMesh-Tcl.
Aeroelasticity
Import an aeroelastic finite element model with Nastran Bulk Data format.
Certification
Framework to plug certification methods to assess margin of safety from the model and result information.
PhysicsAI
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or remeshing and without design variables.
Results Data
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.
Multibody Modeling
MotionView is a general pre-processor for Multibody Dynamics.
Media Files
MediaView plays video files, displays static images, tracks objects, and measures distances.
Tabulate Results
Use TableView to create an Excel-like spreadsheet.
Text Files
TextView math scripts reference vector data from HyperGraph windows to automate data processing and data summary.
Publishing and Reporting
Create, define, and export reports.

Collect Diagnostics Information

The Diagnostics Information Gathering utility collects diagnostics files in the case of a crash and saves them to a common folder.

These files include:

.dmp file(s): Collected by default, or if the HW_CRASH_REPORTS environment variable is set to Normal or Full. If HW_CRASH_REPORTS is set to None, they will not be collected.
HW Log file: Collected if the HW_LOGGER environment variable is set. This environment variable should be set to a file name (like, hyperworks.log); the generated log file will be named hwx_<HW_LOGGER>.
List of environment variables set
Updates and system information

These files will be saved in one of the following locations by default:

Windows: %localappdata%\Temp\AltairCrashFiles_<process_ID> (C:\Users\<user_name>\AppData\Local|Temp\AltairCrashFiles_<process_ID>)
Linux: /tmp/ AltairCrashFiles_<process_ID>

You can specify a directory other than the default, by setting the HW_CRASH_REPORTS_FOLDER environment variable to the desired directory. In this case, the files will be saved in <HW_CRASH_REPORTS_FOLDER>\AltairCrashFiles_<process_ID>.

In the case of a crash, a dialog will open informing you of the location of the files, as well as the environment variable to set to change the location for the future. If the directory cannot be created due to permissions issues, this dialog will not open.

Note:

You must have write permissions for the specified directory in order for the files to be collected.
On Linux, if the specified directory name cannot contains a space, the entire path or the directory within the path which contains the space must be enclosed in quotes (“”).
