Working Model 2D
Working Model is the best selling motion simulation product in the world. Confirm your design with powerful analytical tools. Fast “run-analyze-refine” cycle helps to optimize designs before building physical prototypes. Reduce physical prototyping. You are in total control of the simulation environment. Quickly build, run, and refine simulations with pre-defined objects and constraints. Run, stop, reset, single step, or pause the simulation at any time. Analyze your latest design by measuring force, torque, acceleration, etc. acting on any object. View output as vectors or in numbers and graphs in English or metric units. Import your 2D CAD drawings in DXF format. Input values from equations, sliders and DDE links to MATLAB and Excel. Create bodies and specify its mass properties, initial velocity, electrostatic charge, etc. Run or edit scripts to optimize simulations, document models, and more. Create visually appealing presentations by attaching pictures.

Astah SysML
Astah SysML is a SysML v1 modeling tool for systems engineering and model-based systems engineering (MBSE), developed by Change Vision, Inc. It supports block definition, internal block, requirement, parametric, use case, state machine, activity, and sequence diagrams, plus requirement tables and mind maps.
Designs are stored as models, so a change to a block or requirement is reflected in every diagram that uses it. Profiles, XMI import/export, and data exchange with Cameo Systems Modeler are supported.
AI Chat Copilot works with your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service, and a local MCP server lets external AI agents work with your models.
Astah SysML runs on Windows and macOS. Simulation is not included. A 20-day free trial is available.
For SysML v2, Change Vision offers separate products that run as Visual Studio Code extensions: SysMLv2 Editor and SysMLv2 Modeler (early access).

Simcenter Embed
Simcenter Embed is a Siemens block diagram and state chart environment designed for embedded firmware development and hardware-in-the-loop prototyping. It helps users build, simulate, test, and automatically generate code for embedded control systems. The software supports electric motor control, digital power design, and image and video processing with libraries and on-chip peripheral support. Simcenter Embed reduces manual coding by converting block diagrams and state charts into hardware-ready MCU code. Users can simulate controller and plant behavior, tune controllers offline, and use integrated HIL testing to debug and validate embedded systems on target hardware. With efficient ANSI C code generation, real-time monitoring, and support for popular microcontrollers, Simcenter Embed helps teams speed up embedded system development.

Wolfram System Modeler
Using drag and drop from the large selection of built-in and expandable modeling libraries, you can build industrial-strength, multidomain models of your complete system. Adding the power of the Wolfram Language gives you a fully integrated environment for analyzing, understanding and quickly iterating system designs. Driving insight, innovation and results. Real-world machines and systems are rarely confined to a single physical domain. Models can contain any combination of interconnected components from any number of domains mimicking real-world topology. Exploration is immediate; at the click of a button, you have access to all values from every component in your model. Zoom in to a region of interest and choose from built-in plot styles with a point-and-click interface. Perform your own symbolic and numerical computations by accessing the full model equations and simulation results of your models. Bring the full power of the Wolfram Language to your model analysis.
