bloodflow is on a distinguished road
In a eulerian multiphase model with 2 phases, each phase has an associated wall shear stress (WSS) magnitude. If you want to calculate the total WSS on the surface, is it:

A: TOTAL WSS= Phase.1WSS + Phase.2WSS


B: TOTAL WSS= (Phase1.VOF*Phase1.WSS)+(Phase2.VOF*Phase2.WSS)
