Towards GUI interfaces handling complex multidomain antenna sitting computations

In this paper we describe a new hybrid weak coupling of asymptotic GO/PO techniques and Boundary Element Methods (BEM) based on the FACTOPO Domain Decomposition Methodology (DDM). In that way the modular domain decomposition approach already assessed with exact techniques as BEM and FEM is conserved with the utilization of GO/PO techniques resulting in important reduction of CPU time during parametric studies. Furthermore a graphical user interface (GUI) has been developed in C++ and QT for controlling the computation steps of the multidomain scenario. The accuracy and efficiency of this technique is assessed by performing the computation of the antenna radiation in a multi-domain way cross compared with reference integral equation results.
