All these options make it possible to build a coupling in different ways. Even if the use of the predefined multiphysics coupling interfaces — Nonisothermal Flow and
Conjugate Heat Transfer — is the preferred choice, other alternatives can be of interest in particular cases. This section describes the possibility for coupling heat transfer and fluid flow interface and lists the advantages and limitations of each approach.
See Domain, Boundary, Pair, and Point Nodes for Single-Phase Flow in the
CFD Module User’s Guide for a description of the nodes associated to these interfaces.
