Two-Level Defect-CorrectionMethod for Steady Navier-Stokes Problem with Friction Boundary Conditions
《Advances in Applied Mathematics and Mechanics》2016年第6期932-952,共21页An Liu Yuan Li Rong An 
supported by Zhejiang Provincial Natural Science Foundation with Grant Nos.LY12A01015,LY14A010020 and LY16A010017.
In this paper,we present two-level defect-correction finite element method for steady Navier-Stokes equations at high Reynolds number with the friction boundary conditions,which results in a variational inequality pro...

A Two-Level Preconditioned Conjugate-Gradient Method in Distorted and Structured Grids
《Advances in Applied Mathematics and Mechanics》2012年第2期238-249,共12页Qiaolin He 
The work is partially supported by Youth Foundation of Sichuan University No 2010SCU11072;Doctoral Fund of Ministry of Education of China No 20110181120090.
In this paper,we propose a new two-level preconditioned C-G method which uses the quadratic smoothing and the linear correction in distorted but topologically structured grid.The CPU time of this method is less than t...
