InletStagnationEnthalpyMomentum1Phase

construction:Undocumented Class

The InletStagnationEnthalpyMomentum1Phase has not been documented. The content listed below should be used as a starting point for documenting the class, which includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Boundary condition with prescribed stagnation enthalpy and momentum for 1-phase flow channels.
