About Heat Flux

A heat flux definition consists or two components:

• the transmission surface (defined by the selected part face); and
• a specified magnitude.

A positive heat flux magnitude indicates that heat is flowing into your model across the transmission surface. A negative heat flux indicates that heat is flowing out of your model across the transmission surface.

A heat flux represents a region of your model that is subject to external heating or cooling effects. For example, brake pads pressing on a rotating disc generate frictional heat; a positive heat flux on the disc simulates the heating action of the brake pad.
