from what I’ve read, a regular Stream Tracer filter can’t generate streamlines on 2D slices and a special filter called Evenly Spaced Streamlines 2D has to be used. What’s more, that filter works only when the slice is in XY plane. In one of the previous threads, I’ve found a workaround and used it - creating a slice from 3D domain, saving it vtm file (File → Save Data), then opening in a new instance of ParaView and finally using the Transform filter to rotate the slice so that it lies in the XY plane. So far it all works well and I am able to apply the Evenly Spaced Streamlines 2D filter to that transformed slice. After a few adjustments, I get the desired distribution of streamlines. The only problem is that no matter how I change the parameters of that filter, the streamlines always end too soon, without reaching farther regions of the fluid domain.
Here’s how it looks like, including settings:
As you can see, the lower streamlines don’t even reach the object in the fluid domain while the upper ones pass it but end shortly after that.
The simulation is Christmas-themed by the way
Do you know if anything can be done to make the streamlines propagate through the entire slice ?
