I cant seem to run a stream tracer in the post proccessor.
I’ve followed the steps of making a slice and inserting the same figures but the stream lines are not being generated.
For the online post-processor, please apply the ‘stream tracer’ filter on the default solution source (i.e the first volume source) and not the slice.
Make sure to goto the last solution step and have velocity “U” selected under Vectors in the stream tracer settings.
If using a “line” as Seed Type, make sure the line is inside the volume or if using a “point source” make sure the point coordinates are inside the volume and have an appropriate radius value.

I hope this helps,
