Simulation Analysis of Meshing Characteristic for Cycloid Meshing Drive of RV Reducer
Jixie chuandong, 2017 The cycloid pin wheel drive is essential to RV reducer. It is the basic point to determine the contact stiffness of cycloid and pin wheel. The equivalent contact stiffness is calculated based on Hertz contact theory.

Adaptive mesh refinement for characteristic codes [PDF]
Journal of Computational Physics, 2004 The use of adaptive mesh refinement (AMR) techniques is crucial for accurate and efficient simulation of higher dimensional spacetimes. In this work we develop an adaptive algorithm tailored to the integration of finite difference discretizations of wave-like equations using characteristic coordinates.

Analysis of SDFEM on Shishkin Triangular Meshes and Hybrid Meshes for Problems with Characteristic Layers [PDF]
Journal of Scientific Computing, 2016 In this paper, we analyze the streamline diffusion finite element method (SDFEM) for a model singularly perturbed convection-diffusion equation on a Shishkin triangular mesh and hybrid meshes. Supercloseness property of $u^I-u^N$ is obtained, where $u^I$ is the interpolant of the solution $u$ and $u^N$ is the SDFEM's solution.

Experimental study of the characteristics of a novel mesh suture [PDF]
British Journal of Surgery, 2015 Abstract Background The failure of sutures to maintain tissue in apposition is well characterized in hernia repairs. A mesh suture designed to facilitate tissue integration into and around the filaments may improve tissue hold and decrease suture pull-through.

Adaptive mesh refinement for characteristic grids [PDF]
General Relativity and Gravitation, 2010 I consider techniques for Berger-Oliger adaptive mesh refinement (AMR) when numerically solving partial differential equations with wave-like solutions, using characteristic (double-null) grids. Such AMR algorithms are naturally recursive, and the best-known past Berger-Oliger characteristic AMR algorithm, that of Pretorius & Lehner (J. Comp. Phys.

Fixed mesh refinement in the characteristic formulation of general relativity [PDF]
General Relativity and Gravitation, 2017 We implement a spatially fixed mesh refinement under spherical symmetry for the characteristic formulation of General Relativity. The Courant-Friedrich-Levy (CFL) condition lets us deploy an adaptive resolution in (retarded-like) time, even for the nonlinear regime.
