Python calculator for divergence
 
hi

I want to calculate velocity divergence , I search about it and find Python calculator filter but I can't use it , I run tutorial that there is paraview user guide , but this error shown :

p, li { white-space: pre-wrap; } Traceback (most recent call last):
File "<string>", line 3, in <module>
File "/opt/paraviewopenfoam3120/lib/paraview-3.12/site-packages/paraview/vtk/__init__.py", line 1, in <module>
from vtkCommonPython import *
ImportError: No module named vtkCommonPython




:( please help me .

I assumed you are using OpenFOAM (i don't know why :D, may be because OpenFOAM is accompanied with Paraview)

so if you use OpenFOAM, you can use "foamCalc" to calculate divergence, then show it at paraview
