<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt;">I recommend using the IntegrateVariables filter which will give the correct answer for wedges and pyramids. The output is put into an unstructured mesh with a single vertex cell,
holding the "Volume" in its Cell Data. The implemented is in vtkIntegrateAttributes which triangulates the non-trivial cells into tetrahedra, performing the sum of all volumes within the cell.<br clear="none">

<div>The reason you get a -1 using the python calculator can be linked to the implementation of vtkCellQuality returning this->GetUnsupportedGeometry() (equal to -1) for wedges and pyramids.<br clear="none">
