I have some simulations done with openfoam and have some wind tunnel data, where I have the vertical and streamline velocity. I would like to compare this two with a image including the velocity magnitude contour and streamlines. As I am writing a follow up thesis I would like to do this in the similar manner as my predecessor. I would like to achieve a images such as this:
I am unable so far to generate the streamline on a 2D plot so far. I think there is a python option streamslice, which should enable this. I however do not understand how I can apply this, even after quite a research… Could you give you explain to my the workflow for this?
I also would like to have the same horizontal length scales with x/H and y/H. How can I achieve this?
Sorry if this questions is to simply but I am quite stuck right now.
Many thanks already in advance.
Hi thanks for the quick reply. I tried but I get the following error:
ERROR: In C:\bbd\8fbebceb\build\superbuild\paraview\src\VTK\Filters\FlowPaths\vtkEvenlySpacedStreamlines2D.cxx, line 125

Respective if I use it on z-plane:

My workflow for is so far:
-slice vertical or horizontal plane
- claculate with Calculator : U_XiHat + U_YjHat
- apply EvenlySpacedStreamlines2D
Do I need to do something else?
Can you share your data (and ParaView state file you are using). The horizontal plane should work
streamlines_horizontal.pvsm (575.3 KB)
I hope like this it works. Is there any way to get the streamlines for verticaly planes?
Many thanks for your help and time!
