      - Assign Materials
        Use the Material tool to assign materials to solid bodies.
      - Define Thin Solids
        Use the Thin tool to define thin thermal layers on surfaces and assign material properties.
      - Define Porous Domains
        Use the Porous tool and its satellite icons to define Cartesian, cylindrical, and spherical porosity on solid bodies.
      - Create Sources
        Use the Sources tools to specify a collection of body forces (heat, momentum, or species) within solid bodies.
      - Create Reference Frames
        Use the Reference Frame tool to define rotating reference frames on solid bodies or surfaces.
      - Define Heat Exchanger Components
        Use the Heat Exchanger tool to specify heat exchanger components for a solid.
      - Define Fan Components
        Use the Fan Component tool to model a fan by specifying fan characteristics on a solid.
    - Boundaries
      Define surface boundary conditions.
  - Radiation
    Define radiation conditions and create emissivity models.
  - 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.

Assign Materials

Use the Material tool to assign materials to solid bodies.

From the Flow ribbon, click the Material tool.

Figure 1.
Select solids.
In the microdialog, assign a material model from the drop-down menu or select Material Library to create, edit, and manage custom material models.
From the guide bar, execute the command in the following ways:
- Click to confirm your selection and remain in the tool.
  This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.

Tip:

Click the Material tool satellite icon to view a list of solids in the model and quickly assign materials.
A solid assigned as Void will not be active in the simulation. Utilize this option to run a flow simulation only in a conjugate heat transfer model.
