PIC/FLIP Fluid Simulation - Gravitational Waves
This animation was simulated in a fluid simulation program that I am writing. The program outputs a triangle mesh for each simulated frame which is then imported into Blender and rendered using Cycles.
Simulation visualization was rendered in Blender.
