I want to check the mass continuity equation for simpleFoam/pitzDaily.
I have used

surfaceScalarField phi2 = fvc::interpolate(U) & mesh.Sf();
DivU2=fvc::div(phi2);

to see the divergence of the final Vector field and got following resulting picture (pitzDaily_divU).
There seems to be an error especially close to the boundary, has anyone any Idea why?

B.r., Martin.
