Hi

Does anyone have idea how to compute volumetric flow rate within a cell. usually
surfaceScalarField uu = fvc::interpolate(U) & mesh.Sf() gives the flow rate. but this is only through the surface. to get the volumetric flow rate within a cell, corresponding three surface values must be known. How to know those? Any hints :http://www.cfd-online.com/OpenFOAM_D...part/happy.gif
