An Adaptive Variational Finite Difference Framework for Efficient Symmetric Octree ViscosityACM Transaction on Graphics (SIGGRAPH proceedings), Vol. 38, No. 4, Article 94, 2019 Abstract While pressure forces are often the bottleneck in (near-)inviscid fluid simulations, viscosity can impose orders of magnitude greater computational costs at lower Reynolds numbers. We propose an implicit octree finite difference discretization that significantly accelerates the solution of the free surfac
