FMI—Standardized Model Import

Import models from other types of modeling and simulation tools with the standardized Functional Mockup Interface (FMI).


Mathematica's complete suite for reliability analysis, with functionality for reliability block diagrams, fault trees and importance measures, can now be used with SystemModeler.

Model Development

Strengthened unit support and handling lets you input and display in the unit system of your choice. Copy and paste components among models.

Connectivity & Deployment

FMI—Standardized Model Export

Deploy models with the standardized Functional Mockup Interface (FMI) for immediate use in a large number of tools.

Interactive Simulation Control

Connect to a running real-time simulation from Mathematica; add controllers such as sliders and gamepads; and see real-time plots, gauges and other animations.

User Interface & Documentation

New Documentation Center

The new Documentation Center makes it easy to browse and search all product and library documentation. Extensive cross-linking makes it easy to go from components to examples and more. Text and video tutorials, including the Modelica by Example book, make it easy to learn, whether you are a beginner or an advanced user. Documentation Center

Improved Model Center

The new presentation mode makes Model Center a stronger showcasing environment with full drill-down and live edit capability. Several improvements to workflows, including incremental search of model classes, tabbed model parametrizations and direct simulation, make modeling more efficient.

Improved Simulation Center

Simulation Center has improved performance and workflows, including faster model compilation and concurrent simulation support. Selecting objects in 3D animations now shows variables and parameters, and you can copy simulation results directly with one click on a Mathematica icon.

Linux Support

SystemModeler is now available for all major platforms: Windows, Mac and Linux.

Japanese Localization

SystemModeler is now available with a fully localized user interface and full translated documentation.


SystemModeler is now available in 64-bit versions for Mac and Linux.

Integration with Mathematica

Programmatically Create Models

Automatically create models from equations or control system models. Create structured models by connecting existing components. Or combine both approaches and create components from equations and interfaces and connect them in hierarchies. Cam Design »

Model Diagrams

SystemModeler objects now use model diagrams as their visual representation. Diagrams either show the structure of connected models or an icon. Diagrams can be used together with other graphics, and they can be animated to show system behavior.
Tank Example »

Streamlined Workflow

Use model diagrams to represent your models throughout Mathematica. Automatically use experiment settings for simulations. Other improvements include automatic plot legends, user assistance integration and more.

Key New Mathematica Features for SystemModeler

By using SystemModeler and Mathematica together, you get state-of-the-art modeling and technical computing as an integrated system.

Enhanced Control Systems

Model a plant in SystemModeler, design a controller in Mathematica and automatically put them together. The control system functionality has been enhanced to include automatic PID tuning and support for DAE plant models, as well as delays in plant models and full nonlinear control capabilities.
