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, ...
