Cartesian Grid Adaption in CFD [PDF]
, 1998 We present a single block adaption strategy for 3-D cartesian grids. The adaption process proceeds as an interface with the PHOENICS package. It allows continuous runs or unsteady calculations by reconstructing the interpolated solution on the new mesh at each adaption step.

Bijective Rigid Motions of the 2D Cartesian Grid [PDF]
, 2016 Rigid motions are fundamental operations in image processing. While they are bijective and isometric in $$\mathbb {R}^2$$, they lose these properties when digitized in $$\mathbb {Z}^2$$. To investigate these defects, we first extend a combinatorial model of the local behavior of rigid motions on $$\mathbb {Z}^2$$, initially proposed by Nouvel and ...

LiSBOA (LiDAR Statistical Barnes Objective Analysis) for optimal design of lidar scans and retrieval of wind statistics – Part 2: Applications to lidar measurements of wind turbine wakes [PDF]
Atmospheric Measurement Techniques, 2021 The LiDAR Statistical Barnes Objective Analysis (LiSBOA), presented in Letizia et al. (2021), is a procedure for the optimal design of lidar scans and calculations over a Cartesian grid of the statistical moments of the velocity field.

Anisotropic Cartesian grid adaptation
Fluids 2000 Conference and Exhibit, 2000 A three-dimensional anisotropic Cartesian grid adaptation method has been developed to improve computational efficiency by reducing the number of cells. The method can produce cells with unlimited aspect ratio while keeping the grid reasonably smooth. A test case of 2D supersonic flow around a cylinder shows that the number of cells is reduced to one ...

Link-wise Artificial Compressibility Method [PDF]
, 2012 The Artificial Compressibility Method (ACM) for the incompressible Navier-Stokes equations is (link-wise) reformulated (referred to as LW-ACM) by a finite set of discrete directions (links) on a regular Cartesian mesh, in analogy with the Lattice ...

A Cartesian-grid collocation method based on radial-basis-function networks for solving PDEs in irregular domains [PDF]
, 2007 [Abstract]: This paper reports a new Cartesian-grid collocation method based on radial-basis-function networks (RBFNs) for numerically solving elliptic partial differential equations (PDEs) in irregular domains.
