A Domain Decomposition Method Combining a Boundary Element Method with a Meshless Local Petrov-Galerkin Method
نویسنده
چکیده
A non-overlapping domain decomposition algorithm combining boundary element method with meshless local Petrov-Galerkin method is presented for solving the boundary value problem with discontinuous coefficient in this paper. The static relaxation parameter is employed to speed up the convergence rate. The convergence range and the optimal value of static relaxation parameter are studied, but the numerical results show that the optimal static relaxation parameter is different for different problems. Therefore, a dynamic relaxation parameter is presented for the algorithm. The numerical results show that the number of iteration with the dynamic relaxation parameter is less than that with the static relaxation parameter.
