On Multigrid Methods of the First Kind for Symmetric Boundary Integral Equations of Nonnegative Ordetrie and strongly elliptic boundary integral eguations of nonnegative order. Using a damped Jacobi relaxation scheine, the iterative method proves to be unconditionally convergent in case of smooth boundaries and, moreover, convergent for a sufficiently large number of smoothing steps in case of ge

Effective Preconditioning for Spectral Multigrid Methods,h relatively few degrees of freedom. On the other hand, the matrices involed are full and yield high condition numbers, growing as O(N.) (for polynomials of degree ≤N in each variable). Never-theless the spectral Systems can be efficiently solved using spectral multigrid (SMG) methods. Utilizing FFT

Numerical Solution of Transonic Potential Flow in 2D Compressor Cascades using Multi-Grid Techniquequation in non-conservative form. The work considers a weak formulation of the probiem; for numerical Solution modified Jameson’s rotated difference scheine is used and to simplify periodical conditions we used the locally disturbance form of the governing equation. The resulting algebraic system of
