A mixed Finite Element - Finite Volume formulation of the Black-Oil model

, 1998
.<F3.788e+05> In this paper a sequential coupling of mixed finite element and shock-capturing finite volume techniques is proposed, in order to numerically solve the system of partial di#erential equations arising from the Black-Oil model.

Weak Galerkin finite element solution for fractional Navier-Stokes equations

四川大学学报. 自然科学版
In this paper， the weak Galerkin finite element method is used to solve the time fractional Navier-Stokes equations.A fully discrete scheme is established， where the weak Galerkin finite element is used to discrete the i(i≥1),i-1and i-1 degree ...

A FINITE ELEMENT HETEROGENEOUS MULTISCALE METHOD WITH IMPROVED CONTROL OVER THE MODELING ERROR ∗

, 2015
International audienceMultiscale partial differential equations (PDEs) are difficult to solve by traditional numerical methods due to the need to resolve the small wavelengths in the media over the entire computational domain.

Back and Forth Error Compensation and Correction Methods for Removing Errors Induced by Uneven Gradients of the Level Set Function

, 2002
AMS subject classifications. 65M60, 65M12We propose a method that signi cantly improves the accuracy of the level set method and could be of fundamental importance for numerical solutions of di fferential equations in general.

Three Dimensional Finite Element Modeling of the Earth's Magnetosphere

, 1998
We demonstrate the feasibility of using a nonconforming finite element method on an unstructured grid in solving a magnetospheric physics problem. We use this approach to construct a global discrete model of the magnetic field of the magnetosphere that ...
