Improvements in BondLib, the Modelica Bond Graph Library

Abstract

Bond graphs are a natural method for representing power flows in physical systems and they represent the most basic graphical paradigm that is still fully object-oriented. This paper describes a new version of BondLib, the Modelica bond graph library. The library was created for Modelica with graphical Dymola support, and its object-oriented design allows the wrapping of bond graph models offering a user-friendly environment for modeling physical system in multiple energy domains. The new improvements try to reduce the deployment and training cost for end-users by making the error diagnostics easier.
