Unable to assign a material device in Simulation CFD

Issue:

A material device such as an internal fan, distributed resistance, blower, or rotating region material cannot be applied to a part. Meaning, clicking the Apply button on the Material Quick Edit dialog does not do anything.  Sometimes and error message is presented with the text "no surround fluid near the fan"

Causes:

The likely reason is that the part does not touch a fluid part. Material devices obtain their material properties from adjacent fluid parts. If there is an ambiguity (such as neighboring parts that are all solids), Autodesk® Simulation CFD prevents the material from being applied to the part.

Solution:

To resolve this issue:

Ensure that one or more fluid parts are adjacent to the part in question. Any fluid parts touching a material device should be assigned first before you assign material devices.
