Abstract

In this work the performance and behavior of nonlinear eigenanalysis algorithms on formulation based on the Finite Element Method (FEM) is investigated for structures operating in THz. A technique like the tree-cotree splitting formulation method for the suppression of non-physical solution, the enhancement of the numerical stability and efficiency, is incorporated. Accurate global mesh truncation techniques are also adopted and refined for the eigenanalysis of open structures.
