A list of key new features in System Modeler 13.3.

Modeling

• Create easy-to-install System Modeler Archives with custom libraries and models. »

• Possibility to automatically convert user libraries to be compatible with Modelica Standard Library 4.0.0. »

• Continue working while validating classes and exporting FMUs.

• Edit library versions and dependencies in Class Properties dialog. »

• Automatically add library dependency information when drag-and-dropping components.

• Create custom library groups and organize the models and libraries in the Class Browser. »

• Better feedback and handling when viewing and editing extended classes.

• Better selection of which view to show when opening a class.

Simulation

• Plot expressions of variables. »

• Edit control panels while simulating, restarting the simulation. »

• Optionally show input fields with sliders in control panels.

• Add logarithmic sliders to control panels.

• Interactively change inputs to real-time simulations using control panels.

• Reset control panels to original values.

• Store FFT plots in models. »

• Recompute FFT plots when resimulating. »

• Continue working while building models.

• Stop ongoing model builds.

Computation

• Native System Modeler kernel on Apple Silicon/macOS ARM platform, leading to 30–50% performance improvement in validation and building.

• Native simulations on Apple Silicon/macOS ARM platform, leading to 30–50% performance improvement in simulations.

• Extended security sandbox, allowing more models to be used in the Wolfram Cloud.

• Experimental unit checking, possible to turn on in the Translation view of Options.

• Improved Modelica Language compliance checking.

• Improved zero-crossing handling.

• Visual Studio 2012 is no longer a supported compiler. »
