Research: Simulation

Fluid Surfaces

The standard SPH approach shows severe artifacts at interfaces when simulating multiple fluids with density ratios. These deficiencies are spurious, severe interface tension and instabilities, preventing an animator to simulate turbulently mixing fluids or to control the tension acting between the liquids. We have developed a modified SPH method that corrects for density problems, spurious and unphysical interface tension, and instabilities otherwise present at high density contrast interfaces. High density ratios can now be simulated stably, and the fluid behavior can be controlled according to the simulation problem of interest.
