Class
    Foam::lduCalculatedProcessorField
 
Group
    grpGenericBoundaryConditions
 
Description
    A lduProcessorField type bypassing coupledFvPatchField and holding
    a reference to the Field<Type>.
 
    Used to add updateInterfaceMatrix capabilities to a lduMatrix
    which is fully uncoupled from the fvMesh.
 
    Its functionality is purely to init and update the processor interfaces.
