[OpenFOAM] stream line in 3D geometry with paraview

maysmech · January 27, 2011, 03:55

Hi,
I have a 3D backward facing step. i want see streamline in a face or average of them in z direction. i tested all buttons of Paraview but i didn't reach to a desired one same as attachment picture. i don't have problem for 2D cases. but i don't know how is 3D.

Thanks in advance.

hi
I have the same question like you.So I have chosen tecplot to pose-pocess my results.But I have other question--how to show the streamline at one slice.Have you sloved your plomble?

Hi,

here is an idea:

Let's assume, your slice is in XY direction and with no Z component.

- open "Filters->Alphabetical->Calculator" with your slice as source
- Formula is:
iHat*volPointInterpolate(U)_X + jHat*volPointInterpolate(U)_Y + kHat*0
- Now make a StreamTracer[WithCustomSource] on the Calculator filter.

Nice idea.

Works for me.

Thanks Martin
