Splash in a flash: sharpness-aware minimization for efficient liquid splash simulation

https://doi.org/10.2312/egp20221003

V. Jetly, H. Ibayashi ( April 2022 , Annual Conference of the European Association for Computer Graphics, Eurographics)

We present sharpness-aware minimization (SAM) for fluid dynamics which can efficiently learn the plausible dynamics of liquid splashes. Due to its ability to achieve robust and generalizing solutions, SAM efficiently converges to a parameter set that predicts plausible dynamics of elusive liquid splashes. Our training scheme requires 6 times smaller number of epochs to converge and, 4 times shorter wall-clock time. Our result shows that sharpness of loss function has a close connection to the plausibility of fluid dynamics and suggests further applicability of SAM to machine learning based fluid simulation.
