该方法在使用网格对空间进行离散时使用了 Vertex-centered 方式构建控制体,如下图所示。 两种不同的控制体构建方法 下图显示了一个典型的二维网格。计算域中,所有物理场值和流体属性都存储在单元节点中。以单元节点为控制体中心,围绕该单元节点,将单元边界中点与单元中心依次连接围成的封闭区域即为控制体。 典型的非...
Re: FVM: vertex-centered, cell-centered, or cell-vertex? #3 Nishikawa Guest Posts: n/a Could you explain a bit more about the second part? Vertex-based method is not good for Navier-Stokes? Two-equation models are hard to implement for cell-based method? Thank you, Nishikawa March...

vertex-centered schemepositivity-preservingfinite volumeTwo-dimensional three-temperature(2-D 3-T)radiation diffusion equa-tions are widely used to approximately describe the evolution of radiation energy within a multimaterial system and explain the exchange of energy among electrons,ions and photons.In ...
However, some formulations may introduce either oscillation or diffusion behavior within the vertex-centered (VC) framework. In this paper, a new r-ratio formulation, applied to an unstructured grid in the VC framework, is proposed and compared with the traditional r-ratio formulations. Through ...
A vertex-centered, dual discontinuous Galerkin method This note introduces a new version of the discontinuous Galerkin method for discretizing first-order hyperbolic partial differential equations. The method ... M Berggren - 《Journal of Computational & Applied Mathematics》 被引量: 11发表: 2006年 ...
First it will be shown that the treatment of locally unstructured cells arising from the domain decomposition of such complex geometries - degeneraties are one example- is much more difficult to treat using the cell-vertex scheme than the cell-centered one. The influence of the scheme to ...
What is an equation in the standard form of an ellipse centered at the origin with vertex (-5 0)?Standard Form Equation of an EllipseAn ellipse is a conic generated when we let a plane intersect a cone at angle, forming a bounded curve. The equation of ...

Then, we construct the conservative flux based on the one-side flux by applying the nonlinear combination method, and consequently the equations for the cell-centered unknowns are obtained. At the same time, we need to introduce some equations about vertex unknowns since the vertex unknowns are...
