This is a boundary condition on stagnation inlet and pressure outlet boundaries. It is only available when the Coupled Flow model, Ideal Gas model, Steady model, and Two-Dimensional or Three-Dimensional model are enabled. It is only appropriate to use this option on boundaries of linearly (two-dimensional) or rotationally (three-dimensional) periodic problems in which the flow normal to the non-reflecting boundary remains subsonic. In three-dimensional simulations the boundary must be a surface of revolution. Furthermore, the boundary mesh must be a structured, mapped mesh of quadrilateral faces. In the event these conditions are not satisfied an error will be generated during pre-processing of the boundary mesh prior to application of the non-reflecting boundary condition procedure.
