White Paper: Hybrid Finite Element Boundary Integral Method

By John Silvestro, ANSYS, Inc.

With recent improvements in the efficiency of integral equation solutions it is now possible to combine the integral equation procedure with the finite element method (FEM) in a hybrid Finite Element Boundary Integral approach (FEBI). This paper will discuss the application and advantages of FEBI for solving antenna and scattering problems. A set of benchmarks that demonstrate the accuracy and efficiency of this newly implemented procedure will be presented. Finally 2 examples that use the domain decomposition method (DMM) together with the FEBI will be discussed.
