FlexSim

FlexSim is 3D discrete-event simulation software for modeling and improving existing or proposed systems. Its realistic 3D graphics visualize system behavior, while drag-and-drop controls let users place objects and resources and import CAD drawings or custom 3D objects. Model-building options include a Standard Object Library, Process Flow activity blocks, FlexScript, and C++ integration. For analysis, FlexSim offers charts, graphs, data tracking, and spreadsheet export. OptQuest integration supports scenario optimization using variables, constraints, and multiple objectives. The Experimenter compares scenarios, distributes replications across CPU cores, and supports report generation and performance measures. Data can be imported and exported through Excel and SQL connectors, with FlexScript APIs for files, sockets, and HTTP requests. The Emulation tool supports Modbus, OPC DA, OPC UA, and certain manufacturer-specific PLC connections; some require an Emulation license. FlexSim is listed for Windows and web, with desktop deployment. Pricing is on request; the free Express trial plan has limits including 30 3D objects and 35 Process Flow activities.
