I try to generate streamlines of a harmonic tangent vector field on a smooth surface. I set the source of the tracer as a Poly Points Source. But the streamlines are unexpected short. So I searched for posts here. It’s great that I find this post: Particle Tracing until predefined z-coordinate - #4 by Kenneth_Moreland . I followed the instructions there and tuned the integration parameters. But the behavior of Paraview is quite irreproducible. Different results were obtained for same parameters. Sometimes it generates long streamlines as desired (stop at custom termination conditions), but most of time it stops much too early. And the worst is, after several round of tuning, I can never get it work well any more. I am new to ParaView and I am not sure what mistake I have made. Can someone help me? Why is the behavior of the streamline tracer irreproducible? How to fix it? Thank you very much!
