Ok, this one is more art than scientific visualization, but the stream tracer ribbons in pictures do originate from CFD simulation. This is the OpenFOAM motorbike tutorial case (laminar SIMPLE solution), including the motor bike model (triangulated model → reflections artefacts). The only thing I did was add smooth shading to faces, otherwise model is original.
This is a bit of a breakthrough for me, to get OpenFOAM data via BVTKNodes directly into Blender. Attached also image of node tree. Warning: Reading OpenFOAM cases with BVTKNodes like this has many many limitations. It took me quite some time to make this work.
