Abstract :
In this article, new cascadic algebraic two-grid method for linear finite element equation is designed by use a new iterative condition firstly. Then a new algebraic three-grid method for quadratic Lagrangian finite element equation is proposed by combining the new cascadic algebraic two-grid method with algebraic two level grid for high order finite element equation. The numerical experiment results show that the new algebraic three-grid method is more efficient and robust.
