Modeling Fluid-Solid Heat Transfer

To simulate fluid flow and heat transfer effects in and around structures:

  1. Set up Fluid Flow Conditions to define the inlets and outlets. Specify the temperature of the fluid flowing in.
  2. The fluid material can be assigned to the body or bodies before applying the fluid conditions.
  3. Set up Solid Thermal Conditions, such as Insulated or Temperature, to external surfaces of the solid. A Heat condition can be applied to a surface or a volume. Alternatively, simply select bodies to Include in Simulation if all the external surfaces are going to be convecting, the default Solid Thermal condition.
    All other inputs will be created automatically, these will show as default conditions in the tree, which you can review and adjust as needed.
  4. Optionally, set one or more solid bodies as cutter bodies to automatically block fluid flow.

    Right-click the body in the geometry or model tree and select Cutter Body from the context menu.

    For overlapping bodies, right-click the body in the geometry or model tree and select:

    • Overlapping Bodies > Set as Cutter Bodies to set the body as a cutter body
    • Overlapping Bodies > Exclude from Simulation to exclude the body from the simulation entirely
    • Overlapping Bodies > Identify to launch the Interference tool, which detects and removes interference from clashing bodies
