一种任意比例LTS技术在DG-FETD中的应用
Application of local time stepping strategy with arbitrary ratio for the discontinuous Galerkin FETD method
摘要
Abstract
The discontinuous Galerkin-finite element time domain(DG-FETD) method has the ability to deal with the multiscale problems.The size of time step is limited by the smallest spatial discretization of the simulation domain according to the stability condition when fine structures or high permittivity media occur.To handle this kind of problem,the local timestepping technique with arbitrary ratio is proposed in the paper,which makes the selection of time step size more flexible and reduces the time of iteration.Numerical results demonstrate the correctness and efficiency of the proposed method.关键词
