摘要：
We describe a novel 3D finite difference method for solving the anisotropic inhomogeneous Poisson equation based on it multi-component additive implicit method with a 13-point stencil. The serial performance is found to be comparable to the most efficient solvers from the family of preconditioned conjugate gradient (PCG) algorithms. The proposed multi-component additive algorithm is unconditionally stable in 3D and amenable for transparent domain decomposition parallelization Lip to one eighth of the total grid points in the initial computational domain. Some validation and numerical examples are given.
