plotting streamline for change in alpha.water

canderous · December 14, 2022, 13:49

I'm working on some form of the dam break case, and I'm looking to somehow change the data that streamtracer plots, so that it only shows the streamlines where alpha.water changes from 0 to 1 (so just where alpha.water = 0.5?), i.e. only the surface line of the liquid. How can I achieve this?

I assume you use Paraview?

Hopefully I understood your goal correctly, you could just create a contour at alpha.water = 0.5. There add surface stream tracer?
