A list of key new features in System Modeler 12.3.

Modeling

• Easily enter parameter or variable values in any compatible unit.

• Automatic handling of each keyword when modifying fixed for an array.

• Support for easily making components final to disable further editing when using the class.

• Indication that a replaceable choice is unavailable if the class does not exist.

• Support for WebP image format.

Class Documentation

• Improved listing of components in documentation of connectors and expandable connectors.

• Improved workflow for adding and editing images in the WYSIWYG editor.

• Improved workflow for adding and editing links in the WYSIWYG editor.

• Automatically create Modelica URIs when dropping or pasting file locations into HTML code editor.

• Syntax highlighting in HTML code editor.

• Viewing and editing revision information for classes.

• Remember the collapsed or expanded state of sections when navigating between class documentation pages.

• Include directory listings when generating documentation with links to directories.

• Better display and handling of classes only containing documentation, with support for DocumentationClass annotation.

Simulation

• Add labels to plot markers.

• Plot markers are stored in model plots.

• Tools for adding links and variable references to plot captions.

• Add and edit plot marker locations using units.

• Drag and drop subplots to reorder them.

• Live indicators when snapping plot marker or cursor to min/max values or grid lines.

Computation

• Drastically reduced result file sizes and improved simulation speed.

• Parallel compilation resulting in faster building of models.

• Better handling of linear systems inside torn mixed systems, resulting in simulation runtime improvement.

• Improved function inlining, resulting in drastically improved performance for affected models.

• Improved handling of deeply nested expressions when generating code.
