I have simulated the flow of a liquid that escapes from a container. I used the 'interFoam' solver. I generated the thetrahedral mesh with gmsh, then I converted it with the polyDualMesh utility. The so obtained mesh is funny to use : it increases the calculation speed and reduces the courant number. In my simulation, the liquid flows against a wall and a part of it passes above this wall, and finaly reaches an other container. I have to calculate the volume of liquid that passed above the wall. I thus use the 'integrate variables' filter of paraview in order to integrate the gamma-field in a definite region.

My problem is the following : the 'integrate variables' filter returns an absurd (and negative) volume !!! (but it works well on the initial thetrahedral mesh)... Please, do you know a methods (software), that can calculate the correct volume on this kind of mesh (onbtained with polyDualMesh) ???

Any answer is welcomed...
