Test-Driven Development of a Substructuring Technique for the Analysis of Electromagnetic Finite Periodic Structures

In this paper, we follow the Test-Driven Development (TDD) paradigm in development of an in-house code to allow for finite element analysis periodic type electromagnetic structures (e.g., antenna arrays, metamaterials, and several relevant problems). We use unit integration tests, system tests (using Method Manufactured Solutions—MMS), application (smoke, performance, validation tests) increase reliability shorten its cycle. apply substructuring techniques based on definition a cell benefit from repeatability problem speed up computations. Specifically, propose approach model using only one Schur complement which has advantages concerning other techniques.
