PCNSFVStrongBC

Computes the residual of advective term using finite volume method.

Overview

This object accepts functions describing boundary values for pressure, fluid temperature, and superficial velocity. The superficial velocity functions can also be used to supply superficial momentum information insteady by setting velocity_function_includes_rho = true. If no function is provided for a quantity, the boundary value of that quantity will be determined by extrapolating from the neighboring boundary cell centroid using cell centroid value and gradient information. From this mix of user-provided functions and extrapolated boundary values for pressure, fluid temperature, and superficial velocity/momentum, the fluxes for mass, momentum, energy, and even passive scalars can be computed.
