A New Era of Interated Design Optimization

Increasing the fidelity of modeling has come to the forefront of driving design efficiency.

Yet many of today's tools are limiting: block diagrams that poorly represent key components; models just for simulation, not engineering analysis; and computation that's only basic numerics or that's not integrated at all.

Instead, SystemModeler uses versatile symbolic components and offers an all-in-one integrated workflow, all backed with the ultimate computation environment.

That gets you the power to model reality at high fidelity—driving insight, innovation, and results.

Simplify Your Workflow

SystemModeler implements the Modelica language, which takes advantage of the strengths from component-based modeling, where the flow in components is modeled. This presents significant advantages compared to block-based modeling. This example of constructing an electric circuit illustrates the simplified workflow obtained with component-based modeling:

The Modelica Advantage


Modelica is an open standard language specifically designed for modeling physical systems. It allows individuals and groups to efficiently work together on large-scale projects, constructing reusable custom components and libraries.

Wolfram MathCore is a founding member of the Modelica Association and has taken an active part in the Modelica language design since 1997. SystemModeler is the result of this effort and more than 10 years of close cooperation with customers in the automotive, heavy-machinery, life science, and marine sectors, making it the easiest Modelica tool to use.


Beyond Simulation

A high-fidelity model is useful for much more than just numerical simulation, including everything from optimization and control design to custom visualization and interactivity. Together, SystemModeler and Mathematica provide complete programmatic control of simulations, enabling all kinds of design and analysis.

Uses and Examples of SystemModeler

SystemModeler makes it easy to develop detailed, realistic models in any industry or application area. A core set of physical and logical components is built-in, and custom libraries can be developed to represent the key elements and processes in any domain. Modeling, simulation, visualization, and analysis with Mathematica are tightly integrated, dramatically reducing development time.
Aerospace and Defense   Automotive and Transportation   Heavy Equipment
Model and test complex systems such as unmanned aerial vehicles (UAV), space robotics, and aircraft dynamics. SystemModeler enables system- and component-level design and continuous testing and verification.   Design and simulate vehicle dynamics, powertrain controllers, chassis and safety systems, and more with SystemModeler. Combine with Mathematica for control system design and optimization.   Use SystemModeler to design and simulate heavy machinery with kinematic, dynamic, and thermal behaviors. Perform virtual prototyping, parameter optimization, and other analyses with Mathematica.
Marine   Industrial Manufacturing   Consumer Products
Model ships; underwater vehicles; floating structures; and guidance, navigation, and control (GNC) systems. Apply rigorous analytical techniques to the models using Mathematica.   Model new manufacturing processes prior to implementation or existing ones in order to diagnose problems. Use Mathematica for analyses including pre- and post-processing of models, simulations, and results.   Design home appliances and other electronics systems with SystemModeler and easily incorporate non-electronic elements, such as mechanical assemblies and temperature control, into the complete design.
Energy   Life Sciences   Education
Use SystemModeler to develop accurate models of wind, solar, and other power generation and distribution systems. Combine with Mathematica for further optimization and analysis.   Use SystemModeler for modeling and analysis throughout drug discovery, development, clinical trials, and manufacturing. The flexible environment supports application areas such as systems biology, bioinformatics, and more.   Use the examples from a wide range of application areas to learn about modeling and simulation with SystemModeler and the Modelica language.

Customer Stories



Building the Pod Propulsion Mermaid™ System

As a world leader in ship propulsion development, it is crucial to have an in depth understanding of system dynamics. Therefore we collaborate with [Wolfram] MathCore whenever we need to develop and analyze dynamic models of our systems.
