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
