Parallel higher-order FE-BI-MLFMA for 3D scattering

The finite element-boundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA) has shown to be very general and powerful for 3D scattering. This paper reports our major progress of FE-BI-MLFMA made over the past years. First, we report the study on different approaches of choosing surface in FE-BI-MLFMA. Second, we present the comparison of different algorithms of FE-BI-MLFMA. Third, we compare different higher-order basis functions in FE-BI-MLFMA. Forth, we present the state-of-the art of capability of our parallel FE-BI-MLFMA.
