Based on two-grid discretization,a simplified parallel iterative finite element method for the simulation of incompressible Navier-Stokes equations is developed and analyzed.The method is based on a fixed point iterat...
In this paper the problem−div(a(x,y)∇u)=f with Dirichlet boundary conditions on a square is solved iteratively with high accuracy for u and∇u using a new scheme called“hermitian box-scheme”.The design of the scheme ...
An acceleration scheme based on stationary iterative methods is presented for solving linear system of equations.Unlike Chebyshev semi-iterative method which requires accurate estimation of the bounds for iterative ma...
We consider a mathematical model which describes the static frictional contact between a piezoelectric body and a conductive foundation.A non linear electro-elastic constitutive law is used to model the piezoelectric ...
In this paper,we are presenting a proposal for new modified algorithms for RRGMRES and AGMRES.It is known that RRGMRES and AGMRES are viable methods for solving linear discrete ill-posed problems.In this paper we have...
