Hodge decomposition of vector fields in Cartesian grids. [PDF]
SIGGRAPH AsiaWhile explicit representations of shapes such as triangular and tetrahedral meshes are often used for boundary surfaces and 3D volumes bounded by closed surfaces, implicit representations of planar regions and volumetric regions defined by level-set functions have also found widespread applications in geometric modeling and simulations.

Fully Isotropic Fast Marching Methods on Cartesian Grids. [PDF]
Comput Vis ECCV, 2010 The existing Fast Marching methods which are used to solve the Eikonal equation use a locally continuous model to estimate the accumulated cost, but a discontinuous (discretized) model for the traveling cost around each grid point. Because the accumulated cost and the traveling (local) cost are treated differently, the estimate of the accumulated cost ...

A numerical method for multiphysics simulations based on hierarchical Cartesian grids
Journal of Fluid Science and Technology, 2015 We present a numerical method based on hierarchical Cartesian grids for the simulation of multiphysics problems, here in particular for the conjugate heat transfer between a fluid and a solid.

THE SLICE BALANCE APPROACH USING AN ADAPTIVE-WEIGHTED CLOSURE [PDF]
EPJ Web of Conferences, 2021 In this paper, we present a formulation of the slice balance approach using a nonlinear closure relation derived analogously from the adaptive-weighted diamond-difference form of the weighted diamond-difference method for Cartesian grids.

Cartesian Mesh Generation with Local Refinement for Immersed Boundary Approaches
Journal of Marine Science and Engineering, 2021 In this paper, an efficient and robust Cartesian Mesh Generation with Local Refinement for an Immersed Boundary Approach is proposed, whose key feature is the capability of high Reynolds number simulations by the use of wall function models, bypassing ...
