The Splitting Extrapolation Method of Mixed Finite Element Based on Domain Decomposition;

Since multivariate asymptotic expansions of the approximate error with add power are shown, by means of splitting extrapolations we can not only make use of parallel algorithms to get higher precision approximations, but also obtain the a posteriori estimates.

A splitting extrapolation based on decomposition and d-quadratic isoparametric finite element for solving linear hyperbolic equations with curved boundary is presented and multi-parameter asymptotic expansions of the error of the semi-discrete and fully-discrete finite element scheme are obtained.

Considering the gravity,tension,current force and mooring line extension,the piecewise extrapolating method is employed to the static analysis of the multi-component mooring line.

In this paper, a kind of tree method is proposed to investigate Roos extensions about the reasoning by cases in default logic, discuss deeply the computation of Roos extensions and analyze the relationship between Roos extensions and Reiter s extensions.

A new full discrete stabilized viscosity method for the transient Navier-Stokes equations with the high Reynolds number(small viscosity coefficient) was proposed based on pressure projection and extrapolated trapezoidal rule.
