      The volume flow rate through a surface is defined as the sum of the facet area vector multiplied by the facet velocity vector. The facet area vector is computed by the product of the area magnitude and the normal vector. This can be computed in CFD-Post with an expression using the following synthax: sum(Velocity u*Area*Normal X+Velocity v*Area*Normal Y+Velocity w*Area*Normal Z)@myboundary where myboundary is the boundary of interest
