Hallo I have a problem with perioc rotational interface, and I want to visualize streamlines in the domain. The problem is that the streamlines disappear when they touch the periodic internace but they don't reappear on the other corresponding interface.

I hope my description is clear. What do I have to set or change in the settings to visualize streamline in all the domain ?

thank you to everybody

Go to Derived parts, Streamlines, 2nd order integrator and then increase the max steps and maximum propagation size. Hope that will help you out
