Class
    Foam::calculatedProcessorFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    processorFvPatchField type bypassing fvPatch
 
    Used to temporarily add updateInterfaceMatrix capabilities to a matrix
    during overset solving. Supplies:
    - patchNeighbourField functionality (cached in *this as per
      processorFvPatchField)
    - initEvaluate/evaluate: caching of patchNeighbourField (see above)
    - initInterfaceMatrixUpdate etc: adding of neighbouring data
