generating streamlines with a custom number of source points

ParaView Support

I have a case folder from OpenFOAM with the converged results.
The geometry is simple; one inlet and one outlet, no complex flow at all.
My inlet patch has exactly 100 elements.

I need to be able to generate streamlines from the inlet with an arbitrary number of point sources (which might be larger than the number of my inlet’s elements/cell centers); e.g. I may need to generate 500 streamlines.

That is my current work flow:

  • Load the foam case.
  • Extract inlet patch.
  • Mask points on the extracted inlet block.
  • StreamTracerWithCustomSource (My internal domain as input and masked points as source).

But the problem is that no matter how much I increase the “Maximum Number of Points”, the number of streamline does not increase.
Can someone help me figure a way out?

Thanks

This is expected as the stream tracer cant create more seeds than there is point in your inlet.
A workaround is to ressample your inlet into a more rafined dataset.

You will need to share it if you need more help.

thanks @mwestphal ;
I will share my case by the end of today, if I cannot resolve it by myself.
