The fictitious domain method

  • 114 Accesses


An improved bound is derived on the rate of convergence of the standard difference scheme for solving the Dirichlet problem for the Helmholtz equation in domains of arbitrary shape. The scheme is based on the fictitious domain method. An application of the fictitious domain method and the grid method for solving one nonlinear boundary-value problem is considered. A rate of convergence bound is obtained for the proposed method.
