Design Simulation Technologies Releases Working Model 2D Version 10

Design Simulation Technologies (DST) has released Working Model 2D Version 10. The update introduces an AI assistant that builds simulations from natural language descriptions, a redesigned user interface, and a new COM/Python API that exposes the simulation engine to external automation, the company explains.

Working Model 2D is a 2D kinematic and dynamic simulation tool used by engineers and adopted colleges and universities across six continents. Users build mechanical systems on screen, run physics simulations, and measure forces, velocities, and accelerations on bodies or joints.

Version 10’s AI assistant connects to the simulation engine through the Model Context Protocol (MCP). Users describe a mechanism in plain English—for example, “Build a slider-crank with a 5 cm crank and a 15 cm connecting rod”—and the assistant creates the bodies, joints, and motor and runs the simulation. The assistant can also interpret photographed hand-drawn sketches to generate working models.

“The AI assistant handles the setup work so users can focus on analyzing results and refining designs,” says Alan Wegienka, president of Design Simulation Technologies. Wegienka further explains how the new automation interface makes the simulation engine accessible from C++, C#, Visual Basic, and Python, noting that included Python bindings support parametric studies and automated workflows. Also, built-in script editors for Python and VBScript give syntax highlighting and error reporting inside the application.

Version 10 also adds real-time data exchange with Excel, MATLAB, Python, and user-written DLLs during running simulations. Working Model 2D can function as a plant model for Simulink co-simulation.
