text: 'We introduce a new method for efficiently simulating liquid with extreme
amounts of spatial adaptivity. Our method combines several key components to drastically
speed up the simulation of large-scale fluid phenomena: We leverage an alternative
Eulerian tetrahedral mesh discretization to significantly reduce the complexity
of the pressure solve while increasing the robustness with respect to element
quality and removing the possibility of locking. Next, we enable subtle free-surface
phenomena by deriving novel second-order boundary conditions consistent with our
discretization. We couple this discretization with a spatially adaptive Fluid-Implicit
Particle (FLIP) method, enabling efficient, robust, minimally-dissipative simulations
that can undergo sharp changes in spatial resolution while minimizing artifacts.
Along the way, we provide a new method for generating a smooth and detailed surface
from a set of particles with variable sizes. Finally, we explore several new sizing
functions for determining spatially adaptive simulation resolutions, and we show
how to couple them to our simulator. We combine each of these elements to produce
a simulation algorithm that is capable of creating animations at high maximum
resolutions while avoiding common pitfalls like inaccurate boundary conditions
and inefficient computation.'
