摘要
精确的快速瞬态模拟对天线和设备的设计有相当大的影响.文章针对不连续伽辽金时域(DGTD)方法的混合时间积分格式,提出了一种有效的域分解策略.该策略继承了局部隐式和局部时间步进方法的优点,使用可调整的时间尺度来降低存储和计算的复杂性.数值结果表明了该方法的有效性,证实了该方法可用于复杂结构超高压场线环境下的5G+通信频段快速瞬态模拟.
Abstract
Accurate and rapid transient simulation has a significant impact on the design of antennas and equipment.This article proposes an effective domain decomposition strategy for the mixed time integration scheme of discontinuous Galerkin time-domain(DGTD)method.This strategy inherits the advantages of local implicit and local time stepping methods,and uses adjustable time scales to reduce storage and computational complexity.The numerical results demonstrate the effectiveness of the method and confirm that it can be used for fast transient simulation of complex structures in 5G advanced broadband.
