COMSOL 6.4 - The Heat Transfer Module Physics Interface Guide

	The Nonisothermal Flow, Laminar Flow (nitf) and Nonisothermal Flow, Turbulent Flow (nitf) interfaces found under the Fluid Flow>Nonisothermal Flow branch are identical to the Conjugate Heat Transfer interfaces (Laminar Flow and Turbulent Flow) found under the Heat Transfer>Conjugate Heat Transfer branch. The difference is that Fluid is the default domain node for the Nonisothermal Flow interfaces.

The Nonisothermal Flow, Laminar Flow (nitf) and Nonisothermal Flow, Turbulent Flow (nitf) interfaces found under the branch are identical to the Conjugate Heat Transfer interfaces (Laminar Flow and Turbulent Flow) found under the branch. The difference is that is the default domain node for the Nonisothermal Flow interfaces.
