A PERTURBED BIHARMONIC SOLVER Let us consider the perturbed biharmonic equation. V4u+d:u=f in R, deR, (3) where R is the unit square with the boundary conditions u(x, y) = 0 and u,,(x, y) = 0 for (x, y) ~ fiR, and u,(x, y) is the outward normal derivative at the : G. Lotti. Two methods for solving the biharmonic equation are compared. One method is direct, using eigenvalue-eigenvector decomposition. The other method is iterative, solving a Poisson equation directly at each by: 1.

We present fast methods for solving Laplace’s and the biharmonic equations on irregular regions with smooth boundaries. The methods used for solving both equations make use of fast Poisson solvers on a rectangular region in which the irregular region is embedded. They also both use an integral equation formulation of the problem where the integral equations are Cited by: Stage 1: (Parallel among all processors) After each processor 1 Poisson Solver for Multiprocessors matrix of T and by: A direct method is developed for the discrete solution of Poisson's equation on a rectangle. The algorithm proposed is of the class of marching methods. The idea is to generalize the classical Cramer's method using Chebyshev matrix polynomials formalism. This results in the solution ofN independent diagonal system of linear equations in the eigenvector coordinate Cited by: 2.
