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
