DescriptionWe present an Unsmoothed Aggregation Algebraic MultiGrid (UAAMG) method with a multi-color Gauss-Seidel smoother, which consistently solves the variational viscosity equation within a few iterations. Our framework is up to 14.6 times faster compared to the state-of-the-art adaptive octree solver in commercial software for large-scale simulations of non-viscous and viscous flow.
