Hi everyone! I would like to ask some help regarding the Streamtracer filter with a point cloud.
Can i use it to generate all the streamlines that pass through an arbitraty volume as soon as I enclose this volume inside the point cloud? For example I use it to generate streamlines of a cylindrical domain, by putting all of the cylindrical domain inside the point cloud. Thanks!
You should be able to use the CriticalVolume filter, and then ParticlePathToPathLines filter.
You mean using that After I generate the point cloud streamtracer?
If you already have a point cloud representing moving particle over time, then you do not want to use the StreamTracer at all.
No, the data I have in the cylindrical domain are point data of velocity, of one time step.
Then just generate all the streamlines and select the one that goes though the volume, then use ExtractSelection.
ok, and how do i generate all the streamlines? with a custom source filter?
Using the StreamTracer filter
ok, just to be sure I got it clear: I have a cyclindrical volume, with velocity data for that volume, only for one timestep. To generate all the streamlines that go through this volume I have to place the line source of the streamtracer where? At the outermost point of the cylinder on the inflow side?
There is no concept of “all the streamlines”, You can generate as many streamlines as you want by adding more seed points in the volume.
