Default Wrong Calculation of Cell Volume

Hello all,

for the calculation of the cell volume I use the Python Calculator on Cell Data according to

http://www.vtk.org/Bug/view.php?id=10433#c34084

and i get after Integration of the cell volumes a number like 9.5E-11 whereas the ExtractedBlock (see below) has a volume around 0.017 m and the Threshold estimated around 0.004 m.

I think there is a big misunderstanding on my side how the cell volume calculation works but on the other hand there are reports that the cell area calculation at Ensight-files (here ensight gold) is buggy. My ParaView-Version is 5.0.


My Filters look like

ExtractedBlock
|
ResampleWithDataSet
|
Calculator (calculates Z-Velocities)
|
Threshold (selects only positive Z-Velocities)
|
PythonCalculator (selects Cell Volumes)
|
CellDatatoPointData
|
IntegrateVariables

Thanks for any help in advance

After a while i think the error is a constant factor and so i relate the results to the "real" value.
