INSFVRhieChowInterpolatorSegregated
Computes H/A and 1/A together with face velocities for segregated momentum-pressure equations.
Overview
This object is responsible for generating the following fields for a SIMPLENonlinearAssembly-type segregated solver:
(inverse of the matrix diagonal) which is used as a diffusivity for the pressure equation. This field is stored in a cell-based functor, so centroid values are easy to access but face values need to be reconstructed.
whose divergence is used as a source in the pressure equation. This field is stored in a face-based functor, so face values are easy to access, but cell-center values need to be reconstructed.
This object operates on the matrices and right hand sides of the linearized momentum equations.
