Abstract: Liquid-fabric interaction simulations using particle-in-cell (PIC) based models have been used to simulate a wide variety of phenomena and yield impressive visual results. However, these models suffer from numerical damping due to the data interpolation between the particles and grid. Our paper addresses this by using the polynomial PIC (PolyPIC) model instead of the affine PIC (APIC) model that is used in current state-of-theart wet cloth models. Theoretically, PolyPIC has lossless energy transfer and so should avoid any problems of undesirable damping and numerical viscosity. Our results show that PolyPIC does enable more dynamic coupled simulations. The use of PolyPIC allows for simulations with reduced numerical dissipation and improved resolution of vorticial details over previous work. For smaller scale simulations, there is minimal impact on computational performance when using PolyPIC instead of APIC. However, as simulations involve a larger number of particles and me sh elements, PolyPIC can require up to a 2.5× as long to generate 4.0s of simulation due to a requirement for a decrease in timestep size to remain stable.
