INSFVRhieChowInterpolator
Computes the Rhie-Chow velocity based on gathered 'a' coefficient data.
Overview
This object coordinates everything about an incompressible Navier-Stokes finite volume (INSFV) simulation related to Rhie-Chow. This object performs the following activities
Loops through all momentum residual objects and gathers information related to
coefficients: these are the coefficients that multiply the on-diagonal/current-cell velocity solution in a linearized writing of the momentum equation
Computes the Rhie-Chow velocity according to Eq. (1) when requested by advection kernels or postprocessors

Accessing 'a' coefficient data in nonstandard locations
If you ever come across an error like
Attempted access into CellCenteredMapFunctor 'a' with a key that does not yet
exist in the map. Make sure to fill your CellCenteredMapFunctor for all elements
you will attempt to access later.
then it means an object you're using in your input file is attempting to access Rhie-Chow data in unexpected locations. This can potentially be remedied by setting the parameter pull_all_nonlocal_a = true. This will tell all processes to pull 'a' coefficient data for all elements they have access to (which may not be all the elements in the mesh if the mesh is distributed) from the processes that own the 'a' coefficient data.
