Guide to Coupled Electrostatic-Structural Analyses with Arpeggio
Many applications in micromechanical systems (MEMS) involve electrostatically actuated parts. Arpeggio is a code for facilitating loose coupling between computational mechanics modules in a parallel computing environment. This document describes how to use Arpeggio for coupled elecromechanical analyses using examples commonly encountered in MEMS applications, namely the response of structures to loads imposed by electrostatic fields. For this type of analysis, Arpeggio is used to couple Adagio, a three dimensional finite element code for nonlinear, quasi static or implicit dynamic analysis of three-dimensional structures, with BEM, a boundary integral method code for the analysis of electrostatic fields. This guide describes the methodology used for the loose coupling and the commands the user needs in an input file to perform such an analysis. All commands related to coupled analyses are described and examples are provided.
