Guaranteed Conservation of Momentum for Learning Particle-based Fluid Dynamics [PDF]
We present a novel method for guaranteeing linear momentum in learned physics simulations. Unlike existing methods, we enforce conservation of momentum with a hard constraint, which we realize via antisymmetrical continuous convolutional layers.
