A list of key new features in System Modeler 14.0.

Libraries

• Default to using Modelica Standard Library 4.0.0. Version 3.2.3 is still supported and included during a transition period.

• Modernized bundled examples.

• Possibility to automatically convert user libraries and models to use newer third-party library versions.

• Possibility to create System Modeler Archives that do not permanently install.

• More user choice on loading behavior when installing libraries from System Modeler Archives.

Unit Handling and Checking

• Automatic propagation of units through connections and equations.

• Improved experimental detection of invalid uses of units and display units throughout models, possible to turn on in the Translation view of Options.

• Flexible and automatic conversion of a very large selection of units in input fields and plots.

• Choose preferred unit systems to use globally (SI, Imperial, US, ...).

• Choose preferred display units in library or model.

• Define custom units in libraries and models.

• Unit support when plotting expressions of variables.

• Verification of quantity consistency in connections.

Modeling

• Class rename finds and updates all usages in the complete library, and optionally, in all loaded libraries.

• Component rename finds and updates all usages in the complete library, and optionally, in all loaded libraries.

• Improved rendering of Sphere, VerticalCylinder and HorizontalCylinder fillings in icons and diagrams.

• Improved inference of connection line styling from connector, in particular for Modelica.Clocked.

Simulation

• Snap to intersections between plot curves.

• Choose a default plot theme for all plots.

• Model plots with one end of axis frozen and the other automatically scaling with data.

• Plot axis scaling in model plots, such as Log2 and Log10.

Computation

• Better support for passing functions as arguments to other functions.
