The Modelica Bond Graph Library

Abstract

Bond graphs offer a domain-neutral graphical tech-nique for representing power flows in a physical sys-tem. They are particularly powerful for representing systems that operate in multiple energy domains, such as thermal models of electronic circuits, me-chanical vibrations in acoustic systems, etc. A bond graph library was created for Modelica with graphi-cal Dymola support. The library is presented in this paper. Applications from different domains are of-fered to document its use.
