Abstract

To eliminate the bottleneck of finite element-boundary integral-multilevel multiple algorithm (FE-BI-MLFMA) proposed for scattering by large and deep cavities^[1], a parallelization approach is presented and implemented. To demonstrate the capability of this parallel FE-BI-MLFMA, a variety of large and deep complicat-ed cavities have been computed, including a circular cavity loaded by an array of straight blades model, a circular cavity with nonuniform parts and a large and deep open brick cavity with 15 λ × 15 λ × 100 λ. Numerical experiments verify the high efficiency of this parallelization approach.
