[General] Best way to get data from Python into ParaView

MalteJ · July 16, 2013, 10:45

Hi,

I have coded a geometry generator in Python and am doing some calculations.
Now I'd like to visualize the results in ParaView. The data I want to exchange is the geometry itself as a structured quad mesh and as an unstructured tri-mesh. Further the surfaces have some values associated (scalars and vectors).
In ParaView I want to do some contour plots, deformation animations etc.

What is the best way to get my data out of Python into ParaView?

Thank you very much!

Malte

I know I briefly saw something on this topic... I can't seem to find what I think I saw. Nonetheless, here are the few things I could find:

Best regards,

Hi Bruno,

thank you for your reply!
I suspected VTK Files are the way to go but wanted to be sure before I am running the completely wrong direction.
Thanks for the links!

Best regards,
Malte
