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.
      - Set Up the Thermal Radiation Settings
        Use the Physics tool to turn on thermal radiation physics and define the thermal radiation settings used in the simulation.
      - Define Surface Finish Models
        Use the Surface Finish Library tool to create, delete, and import/export surface finish models. A surface finish definition is an ideal grey-surface emissivity model used in the radiation equation.
      - Define Default Surface Conditions
        Use the Defaults tool to define global surface conditions for thermal radiation.
      - Assign Surface Finishes
        Use the Surface Finish tool to apply surface finish properties to selected surfaces.
      - Define External Radiation
        Use the External tool to apply external radiation heat transfer to selected surfaces or thin solids.
      - Define Radiation at Openings
        Use the Opening tool to apply radiation boundary conditions at openings. A radiation opening definition provides a method of fully enclosing a fluid domain that is not surrounded by walls. This condition is appropriate for inlet and outlet type boundary surfaces.
      - Define Radiation Output
        Use the Output tool to apply radiation output settings to selected surfaces.
    - Participating Media
      Define participating media radiation conditions.
    - 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.

Assign Surface Finishes

Use the Surface Finish tool to apply surface finish properties to selected surfaces.

Surface finish includes emissivity and diffused fraction properties.

From the Radiation ribbon, click the Surface Finish tool.

Figure 1.
Select surfaces.
In the microdialog, assign a surface finish from the drop-down menu or select Surface Finish Library to create, edit, and manage custom surface finish 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.
