A cell-centred finite volume method for the Poisson problem on non-graded quadtrees with second order accurate gradients
(Elsevier, 2017-02-15)This paper introduces a two-dimensional cell-centred finite volume discretization of the Poisson problem on adaptive Cartesian quadtree grids which exhibits second order accuracy in both "the solution and its gradients, ... -
Preserving Geometry and Topology for Fluid Flows with Thin Obstacles and Narrow Gaps
(Association for Computing Machinery, 2016-07-01)Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices ...
