Highlights in System Modeler 14.3
Validate Design Specifications
With System Modeler 14.3, you can automatically validate your design against performance and safety requirements. Using the power of a complete specification language and a suite of fully automated Wolfram Language functions, you can check behaviors over time, manage uncertainty and catch edge-case failures – early in the design process.
Example: Validating Thermal Runaway Risk in Process Plants
Example: Validating Battery Safety and Performance Requirement
Example: Validating High-G Aerobatic Maneuvers
Model, Simulate, Plot & Analyze Using Calendar Time
System Modeler 14.3 lets you use a date picker to set simulation periods and plot results on real-world date-time axes, delivering clearer, context-rich insights.

Visualize Model Configurations in Diagrams
With System Modeler 14.3, you can create icons that automatically update based on configurations—making setup of complex systems easier to understand, explore and validate at a glance.
Model Heating and Cooling Systems in Buildings
Design energy-smart buildings with the open-source IBPSA library. Simulate building HVAC and district heating or cooling networks using 100+ validated components—ideal for energy analysis, control design and research.
Model Residential & Utility-Scale PV Generation
Analyze integration of PV systems in buildings, microgrids and hybrid energy systems using the open-source PhotoVoltaics library. Use detailed simulation of cells, modules and full-scale plants with realistic temperature and irradiance effects.
PhotoVoltaics Library
Example: PV Module: Effect of Varying Irradiance
Example: Predict Energy Production Using Data-Driven Models
Model the Resilience of Power Infrastructure
Plan and analyze AC, HVDC and variable-frequency grids with adaptable components and replaceable phase systems using the open-source Power Grids and Power Systems libraries. Ideal for grid planning, reliability assessments and renewable energy integration.
Modelica Standard Library 4.1
With the Modelica Standard Library version 4.1, you can access new components for tasks like signal tracking and benefit from improved features such as CSV table input—expanding your modeling capabilities in System Modeler 14.3.
Live Tuning and Calibration
Adjust gains, time constants or physical parameters on the fly – without restarting the simulation in System Modeler 14.3. Quickly explore design variations, run what-if tests and see system responses instantly, saving time and boosting insight, even in large or long-running models.
Git-Friendly Formatting
System Modeler 14.3 lets you format your models your way – preserving custom layout, comments and whitespace. Enjoy cleaner diffs and effortless collaboration through GitHub and other version control platforms.
