In this paper, we will discuss the cascadic multigrid **preconditioned conjugate gradient** method for the linear finite element approximation of the second order elliptic boundary value problem -[nabla]*(w[nabla]u) = f, in [OMEGA] u = [g.

of Macau) stick to the practical as they introduce students to iterative methods for solving Toeplitz systems based on the **preconditioned conjugate gradient** method.

n] related to a continuous generating function f(x) there exist various preconditioning techniques that ensure fast convergence of the **preconditioned conjugate gradient** (pcg) method; see [2, 7] and the references therein.

Beginning in 1994, ANSYS added a Jacobi **preconditioned conjugate gradient** solver (JCG) and subsequently an Incomplete Cholesky **Preconditioned Conjugate Gradient** solver (ICCG) to improve thermal analysis capabilities.

In that paper, a **preconditioned conjugate gradient** iteration with a block diagonal preconditionerwas used to solve the system of [P.

This system can be solved with a **preconditioned conjugate gradients**, where the matrix-vector product is only implicitly given.

We consider a class of such methods, where the multigrid only appears as a black-box tool for constructing the preconditioner of the stiffness matrix, and the base iterative algorithm is one of well-known off-the-shelf preconditioned gradient methods such as the locally optimal block **preconditioned conjugate gradient** method.
