Materials

Verify the material of the working fluid.

  1. In the Outline View, expand Setup > Materials > Fluid.

  2. Double-click air.

    The Create / Edit Materials dialog opens, with Name set to air.

  3. Under Properties, verify that the Density is set to a constant of 1.225.

    This setting specifies that the air is incompressible (that is, it has a constant density.)

  4. Click Close to exit the dialog.
