Hi everybody!

I postprocess results from a LES simscale simulation in paraview. My aim is to show how wind is flowing around two different shaped walls in a small landscape architecture project.

I worked with streamline filters and applied them in three different ways (see pdf attached):  
1: twelve linear sources, each with a distance of 50cm (z value)  
2: twelve linear sources, following the topography, each with a distance of 50cm (z value)  
3: three spheres.

Which one do you think gives the best result?

Thank you!
