Domain Decomposition Method and Model Order Reduction Method for Electromagnetic-Thermal Coupled Problem

摘要

A numerical simulation for electromagnetic heat induction is performed. Domain decomposition method is combined with model order reduction for the calculation of electromagnetic thermal coupled problem. Model order reduction (MOR) based on Proper Orthogonal Decomposition (POD) is used to find a low-order approximation to the original high order problems such that the computation could be improved effectively. Also a non-overlapping domain decomposition method is used to partition the calculation domain into two subdomains for simplicity. A serial staggered coupling strategy is used to solve the coupled problem. The simulation result is verified with that of simulation case contained in the COMSOL application library. The aim of this paper is to provide an approach to promote the computation efficiency of Multiphysics simulation.
