Set Up the Simulation Model

Use the Physics tool to define the global AcuSolve settings used in the simulation.

Based on the selected model, required attributes in domains and boundaries will change.

  1. Open the Physics tool in the following ways:
    • From the Flow ribbon, Setup tools, click the Physics tool.


      Figure 1.
    • Right-click in empty space in the Setup Browser and select Global Settings.
    The Setup dialog opens.
  2. Define the physics models and their parameters.
    • Time
    • Flow
    • Heat transfer
    • Multifluid
  3. Click Solver controls and define the solver settings.
  4. Click Reference values and enter values for the fields shown.

Set Up Multiphase Modeling

  1. From the Flow ribbon, Setup tools, click the Physics tool.


    Figure 2.
  2. Click Multifluid under Settings.
  3. Change the Multifluid type to Immiscible.
  4. Select a field interaction material model from the drop-down menu or click Material Library to create, edit, and manage custom material models.
    After setting up the multiphase physics, you have the option to choose the incoming fluid when defining inlet boundary conditions.


    Figure 3.
    In addition, you can select the fluid as a variable when defining initial conditions in the Solution ribbon.

Set Up Humidity Modeling

  1. From the Flow ribbon, Setup tools, click the Physics tool.


    Figure 5.
  2. Click Heat Transfer under Settings.
  3. Activate the Heat transfer option.
  4. Click Multifluid under Settings.
  5. Change the Multifluid type to Humidity transport.
    After setting up the humidity physics, you have the option to define the humidity input when creating inlet boundary conditions.
