Jawset TURBULENCE.2D v1.2.6 for After Effects CS5/5.5 (Windows)
In TURBULENCE.2D, obstacles are solid objects that do not flow. They affect
the fluid but the fluid does not affect
them. You can use arbitrary shapes as solids - buckets, paddles, walls, ramps or text. The image below shows and example of text as a solid object, that forces green vapor to flow around it.
