Hi dear OpenFOAMers,
I am trying to generate streamlines in Paraview in some domain where I have just simulated the fluid flow. As far as I see, the only possible seed types (where the streamlines will have their origins) are Point Source and Line Source. For me it would be quite naturally, however, to generate streamlines starting, for example, from the inlet, i.e., by taking it as an area source. Is it possible in Paraview? I work now with the version 3.8.0, under Linux SuSE 11.

Regards,
Alexey Kochevsky

Hi Alexey,

it is possible in Paraview:

- Separate your inlet face (for example via foamToVTK or File->Save Data or Filters->Alphabetical->Slice ...) so that you have it listed in the Pipeline Browser as a selectable object.
- Select filter "Filters->Alphabetical->Stream Tracer With Custom Source", as "Input" select your simulation results, as "Source" select your inlet face.

Hi Martin,
thank you very much, it is exactly what I needed. Paraview seems to be still more powerful than I thought before.

Regards, Alexey

Sorry for the reaaaaaally late reply, but I only found out about this recently - what you're looking for is the "surfaceLIC" plug-in: Limiting streamlines using surfaceLIC plugin

Hi,

I have created streamlines from an area source, but the results is far from the expected. This is the pressure field of the flow through a cubic sample of rock. Inlet is at left, outlet at right. All the other four faces are walls.

I can display velocity vectors coloured by their magnitude. Then, I extract a plane near the inlet and use it to create the streamlines:

As you can see comparing the streamlines with the velocity field, the streamlines don't show the trajectories that lead the fluid from the inlet to the outlet, let alone the two high speed paths that can be seen in the velocity field image.

I have already tried tweaking the properties of the streamlines in all ways I could imagine.

Do you have any suggestion on how to display them properly?

Thanks, Thomas
