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.
- 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.
  - Command Line Options
    This topic summarizes the command line options that are supported by hwCFDReport.
  - Input File Commands
    This topic describes the input file commands that are supported by hwCFDReport.
    - BAR_CHART
      Bar chart of specified quantities.
    - COVER_PAGE
      Defines the cover page that will be included within the output report.
    - CUT_PLANE
      Visualization surface along x, y or z.
    - DATASET
      Defines the type and location of data to use for the report generation.
    - DISPLAY
      Defines the display parameters of the images created during the report generation.
    - GSP
      Performs general signal processing for aeroacoustic analysis.
    - IMAGE
      Image is used to capture image of specified quantity.
    - ISO_SURFACE
      A 3D surface representation of points with equal values in the model space.
    - LINE_PLOT
      Graphical 2D plot of quantities.
    - PART
      A collector for one or many components used to toggle on and off views.
    - STREAMLINE
      Streamlines are massless particles moving along a path with a velocity tangent to the streamline at every point.
    - SURFACE_STREAMLINE
      Surface streamlines are massless particles moving along the surface of an object or plane with a velocity tangent to the streamline at every point.
    - VARIABLE
      Expressions are used to define a quantity in terms of variables that are defined using the VARIABLE command or in terms of built in math functions (sin, cos, tan, and so on). The order in which commands appear is not important. Variable x could be a function of variable y, even though it appears afterward in the input file.
    - VIEWANGLES
      Defines custom views that can be accessed within the IMAGE command.
    - VIEW
      Specified view by user to allow for legacy support of a restart file.
  - Automatic Report Generation Examples
    Use hwCFDReport to create a .pptx or .pdf report with user defined visualization.

LINE_PLOT

Graphical 2D plot of quantities.

Syntax

LINE_PLOT(“name”) {parameters}

Qualifier

User-given name

Parameters

name (string): User-given name of the command. The instance of a given command is referenced using this parameter.
