On the Finite Element Tearing and Interconnecting Method for Scattering by Large 3D Inhomogeneous Targets

The finite element tearing and interconnecting method (FETI) is applied to compute scattering by large 3D inhomogeneous targets. Two algorithms of FETI have been implemented for 3D scattering. The performance of these two FETI algorithms has been investigated in detail, particularly for large inhomo...
