Welcome
What's New
View new features for HyperMesh CFD 2025.1.
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 Repair
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.
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.
Automation
Automate simulation processes with templates and utility scripts.
- Template Manager
  Use the Template Manager to define rule-based logic for groups, geometric operations, and setup and automate simulation processes.
- Python API
  Use python based automation to quickly setup HyperMesh CFD for ultraFluidX simulations in batch mode.
  - Case Setup Python API
    Documentation of HyperMesh CFD for ultraFluidX simulation case setup.
    - Load Data
      Use basic Inspire API to load data.
    - Tunnel
      Create a wind tunnel.
    - Turbulence
      Create a turbulence generator.
    - Part Types
      Identify parts.
    - Belts
      Create a belt system.
    - Mesh Controls
      Create mesh refinement zones.
    - Result Outputs
      Define result output types.
    - Material
      Create a new fluid material.
    - Output Controls
      Set output parameters.
    - Simulation Controls
      Set simulation parameters.
  - precursorRun Script
    The precursorRun script is a standalone command line utility that generates the .xml input files to run two simulations: a precursor ultraFluidX simulation with coarser mesh and fast turnaround time and a user desired ultraFluidX simulation starting from the results generated by the precursor simulation.
- hwCFDReport
  Post-processing utility that uses results from CFD simulations to generate a PowerPoint report containing images, animations, and graphs of the results from the simulation.
