Abstract
A multi-region formulation between Finite Element- Boundary Integral (FE-BI) regions and perfectly electric conducting (PEC) boundary element method (BEM) regions is presented. The method proceeds by first transforming the problem into a PEC equivalent one using a custom direct matrix solver within FE-BI regions, and then solving for the electric currents residing on FE-BI and BEM regions iteratively. The full field solutions within those ‘PECfied’ FE-BI regions can then be recovered using those electric currents and the matrix factors from the previous steps. Numerical results for two-dimensional radiation problems are presented.
