The High Number Flow, Algebraic yPlus (hmnf) interface () is found under the High Mach Number Flow>Turbulent Flow branch () when adding a physics interface. This is a predefined multiphysics interface which combines The Turbulent Flow, Algebraic yPlus Interface for compressible flow with The Heat Transfer Module Interfaces.

A detailed description of the High Number Flow, Algebraic yPlus (hmnf) interface, which models turbulent gas flows in the transonic and supersonic range, is analogous to The High Mach Number Flow, k-ε Interface and The High Mach Number Flow, Spalart–Allmaras Interface.
