What's New in Wolfram SystemModeler 4.3

What's New in Wolfram SystemModeler 5.0 | 4.2 | 4.1 | 4.0

A list of key new features since SystemModeler 4.2.


  • Easy sharing of complete models, including all dependencies (libraries, shapes, tables, code, etc.).
Click for copyable input
  • Package models with stored plots, which will immediately be shown when simulating.


  • Ability to create and use stored plots in Simulation Center.
  • Support for custom units for plots and parameters in Simulation Center.
  • Explicit indications given when parameter values cannot be changed.
  • Improved model compilation speed for large models of up to 40%.


  • Documentation now includes complete listing of example uses for each component.
Click for copyable input
  • Improved diagram editor, making it easy to add points to connection lines for neat model diagrams.
  • The diagram editor now automatically brings up color, file and port picker dialogs when appropriate.
  • Complete coverage of all Modelica syntactical errors, with detailed diagnostics.


  • SystemModeler educational and industry examples are now bundled with the product.
  • All SystemModeler examples have been updated with stored plots for immediate use.
  • Updated Modelica by Example book.

Wolfram Language Integration
