Specifying a Convection Condition

To specify convection:
  1. Select Convection from the dropdown menu of the Thermal tool in the Physics group of the Simulation tab, or by selecting the Convection tool in the Thermal condition HUD.
  2. Select faces that are on the exterior of the model.

    If your model contains Named Selections, you can click Advanced filters, select Link named selections, and choose one from the list.

  3. Enter the Convection Coefficient (or heat transfer coefficient).
    This value is based on the composition of the fluid in contact with the face, the geometry of the face, and the hydrodynamics of the fluid flow past the face.
  4. Enter the External temperature of the surrounding fluid.
