Geometry Modeling
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.
- General Setup
  Prepare your model for a general AcuSolve simulation.
  - Flow
    Set up the simulation model, materials, domains, and boundaries.
  - Radiation
    Define radiation conditions and create emissivity models.
    - Thermal Radiation
      Define thermal radiation conditions.
    - Participating Media
      Define participating media radiation conditions.
      - Define Participating Media Models
        Use the Model tool to create, delete, and import/export participating media models.
      - Assign Participating Media
        Use the Assign tool to apply participating media properties to selected solids. Solids which are not assigned any participating media model are considered as non-participating.
      - Define Participating Media Interface Surfaces
        Use the Interface tool to define diffusion properties of interface surfaces across participating media.
      - Define Participating Media External Boundaries
        Use the External Boundary tool to define diffusion and refractive properties of wall surfaces of participating media.
    - Solar Radiation
      Define solar radiation conditions.
  - Motion
    Define direct, derived, and constrained mesh motion.
  - Solution
    Define output conditions, run the simulation, and view the results.
  - AcuTrace
    AcuTrace is particle tracer that runs as a post-processor to AcuSolve.
- Aerodynamic and Aeroacoustic Setup
  Prepare your model for wind tunnel analysis using ultraFluidX.
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.

Participating Media

Define participating media radiation conditions.

Important: To consider the effect of media between surfaces, you can set the radiation model to P1 Model or Discrete Ordinate in the Thermal Radiation Physics tool. One of these models must be selected if you are going to define any participating media.
