FluxVariables is a misnomer
The classes [...]FluxVariables
actually computes fluxes for which it uses variables from the VolumeVariables
and FluxVariablesCache
. It does store local variable objects in its state but the main interface is all about computing fluxes. Also, they are used directly within LocalResidal::computeFlux
as a helper to compute fluxes (evaluate the flux-part of the local residual).
Possible better names would be [...]Flux
[...]Fluxes
.
