A list of key new features in System Modeler 12.2.

Modeling

• Extended GUI support for Modelica
• Full graphical support for editing each and final keywords.

• Show parameter values using chosen display unit in icons.

• Strict Modelica compliance
• More pedantic rejection of noncompliant Modelica code.
• More informative error messages for invalid Modelica code.

• Modelica Standard Library
• Now including Version 4.0.0.
• Version 3.2.3 updated to build 4.
• Experimental support for the Modelica.Fluid library.

• Improved user experience when using expandable connectors.

• User-selectable name when lifting parameters and variables.

• Add SVG files to icons and diagrams of models.

• Preserve line endings when saving and use line endings for the user's platform by default.

• Improved performance when saving packages with many classes.

Simulation

• Custom simulation time unit in experiments and plots.

• 3D Animation
• Orientation indicators on visualization shapes.



• Improved zoom controls, including drop-down with common choices.
• Improved selection handling.
• Support for Vector primitive from Modelica Standard Library 4.0.0.

• Plotting
• Moving of variables between subplots by drag-and-drop or right-click on curve.
• Intelligent display of arrays when selecting variables to plot.



• Captions can be added to plots, including variable values and references to subplots.



• Identifiers for model plots, for identification in Wolfram Language and captions.
• Make event transients identifiable in plots using a lighter color.



• Duplicate plots for easy modification and experimentation.
• Prefetch variables in model plots for fast and efficient plotting from large simulation results.



• Better control of result when exporting plots to images.

• Improved display of simulation logs.

Computation

• Improved FMU Export compliance.

• Improved Modelica compliance of discrete-time variable initialization.

• Hundreds of bug fixes for improved stability, messaging and performance.
