Subdomain solution decomposition method for nonstationary problems
نویسندگان
چکیده
The reduction of computational costs in the numerical solution nonstationary problems is achieved through splitting schemes. In this case, solving a set less computationally complex provides transition to new level time. traditional construction approach schemes based on an additive representation problem operator(s) and uses explicit-implicit approximations for individual terms. Recently (Efendiev Vabishchevich (2021) [22]), class methods approximate has been introduced decomposition not operators but itself. This with subdomain selection used paper construct domain boundary value second-order parabolic equation rectangle difference approximation space typical. Two three-level without overlapping subdomains are investigated. Our experiments complement theoretical results.

1. Introduction. We present a domain decomposition (DD) method to solve scalar advection-diffusion-reaction (ADR) equations which falls into the category of iteration-by-subdomain DD methods. Domain decomposition methods are usually divided into two families, namely overlapping and non-overlapping methods. The former are based on the Schwarz method. At the differential level, they use alternati...

We present a new parallelizable preconditioner that is used as the local component for a two-level preconditioner similar to BPS. On 2D model problems that exhibit either high anisotropy or discontinuity, we demonstrate its attracting numerical behaviour and compare it to the regular BPS. Finally, to alleviate the construction cost of this new preconditioner, that requires the explicit computat...
متن کاملDomain Decomposition Method for Parabolic Problems
Domain decomposition methods are widely used to solve the parabolic partial differential equations with Dirichlet, Neumann, or mixed boundary conditions. Modified implicit prediction (MIP) algorithm is unconditionally stable domain decomposition method. In this paper, the SOR iterative technique is applied to the MIP algorithm and the optimum over-relaxation parameter is provided.
