摘要 针对多区域伪谱时域算法(MPSTD)中子域分界面两侧为不同介质的情形,提出了特征变量物理边界(CVPB)子域分界面匹配条件,然后在总结现有子域分界面匹配条件的基础上,分别比较了子域分界面两侧为相同和不同介质时各种子域分界面匹配条件的稳定性。数值仿真表明,在子域分界面两侧为相同介质材料时采用特征变量法匹配条件,而在子域分界面两侧为不同介质材料时采用CVPB匹配条件,可使得MPSTD算法稳定性最好。 For subdomains with different materials in multidomain pseudospectral time-domain (MPSTD) algoritm, a characteristic variables-physical boundary (CV- PB) matching condition is proposed in this paper. In cases of subdomains with different materials or same materials, the traditional and the presented matching conditions are comparied and analyzed. The numerical results show that the CV-PB matching condition is more stable for the boundry separating two subdomains with different materials and the characteristic variables matching condition is more stable for the boundary separating two subdomains with same materials in MPSTD.
