I’ve got a problem. I have to do movie of several fixed stream lines evolution.
I have 100 3D arrays with velocity vector field, what correspond to 100 time steps in modilling the fluid. So, I used stream tracer on the whole bunch of them, but it establish line start points randomly somewhere in the middle of the sphere for each array and I can’t watch the evolution of a fixed line.
How can I fix line start points?
Thanks in advance!
