Simbus Ltd (https://simbus.com/) has released an update of its product family. The new release (SR2022.0.2.1) brings improvements to Simbus Bondgraphs^TM for intuitive, energy-based modeling and simulation of multidomain physical systems in the MATLAB^® and Simulink^® platforms from MathWorks®. These improvements include more robust handling of physical systems whose mathematical descriptions include derivative operations. These systems are often encountered in mechanical engineering (especially for multibody systems) as well as in other domains where certain modeling approximations have been made.

Simbus Bondgraphs (https://simbus.com/products/simbus_bondgraphs/) enables engineers in multidisciplinary teams to develop integrated models easily using a domain-neutral, energy-based notation, in a common modeling framework. Simbus Bondgraphs implements the bond graph notation for dynamic systems representation.

Simbus Bondgraphs provides:

• An intuitive library of blocks for the rapid creation of multidomain physical system bond graph models in Simulink;

• A toolbox of supporting MATLAB functions that provides a powerful scripting capability for interacting with bond graph models;

• Support for linear, nonlinear, and data-driven modeling;

• Easily-accessible documentation suitable for engineering practitioners, academics, and students;

• A substantial collection of examples to get engineering teams started quickly.

Bond graphs were formulated at the Massachusetts Institute of Technology and have been adopted worldwide by academic, teaching, and research institutions as well as in industries as diverse as aerospace, marine, automotive, public transportation, robotics, energy production and transmission, material and chemical processing, heavy machinery, agriculture, and biological and health sciences.

The development of Simbus Bondgraphs has been motivated by the need to supplement model-based systems engineering (MBSE) in teaching, research, and industry with physical modeling capability. Increased adoption of MBSE means that engineers from different disciplines are working together more closely than ever, especially in early-stage design. Simbus Bondgraphs lowers the barriers between these disciplines and aids multidisciplinary collaboration with increased productivity.

Simbus Bondgraphs can be used for developing physical models to aid in the design and evaluation of control systems, prognostic and diagnostic systems, fault-recovery and isolation systems. Simbus Bondgraphs can also be used for failure modeling, system architecture design, parameter optimization, and also for developing elements of digital twin models. Simbus Bondgraphs also aids greatly in the teaching and learning of physical systems modeling at the undergraduate and graduate levels due to its intuitive, energy-based representations.

Simbus products are currently compatible with the R2021b, R2022a, and R2022b MATLAB and Simulink product families running on Windows^® 10, Windows^® 11, Ubuntu^® 18.04 LTS, and Ubuntu^® 20.04 LTS. Support for Apple^® platforms is planned for a future product release.
