Novel adaptive locally implicit scheme of the discontinuous Galerkin time-domain method for distributed transient simulation of antennas and resonance models

[摘要] An efficient distributed adaptive locally implicit scheme for the discontinuous Galerkin time-domain method is proposed in this letter. In comparison to the traditional methods, the proposed method employs an adjustable time scale to adaptively reduce storage and computational complexity. The implicit and explicit regions are distributed into the local storage of nodes to achieve load balance between them. Numerical results demonstrate the effectiveness of this method and confirmed that it can be used for the fast transient simulation of resonance models.
