Create Standalone FMU
Use the FMU Builder for Simulink support package to create a Functional Mockup Unit (FMU) from Simulink models or C/C++ code.
Debug FMU that contains its source code using an external debugger. For more information, see Debug FMU with Source Code Using External Debugger.
To import your existing FMU into Simulink, see FMU Importing.

Featured Examples
Export Simulink Model to Standalone FMU
Export Simulink® component to standalone Co-Simulation FMU 2.0 with Simulink Compiler™. For a detailed explanation of the model, see:
Generate Model Exchange FMU from Simulink Model
Generate a standalone model exchange FMU, compatible with FMI 2.0 standards, from a Simulink® model. A model exchange FMU only contains the equations for the mathematical model of a system. It uses the solver of the FMU importer for solving its system equations during simulation.
Export Simulink Model to FMU with Variable Step Solver
Demonstrates how to generate a Functional Mockup Unit (FMU) from a Simulink® model that uses a variable step solver. Export a Simulink model to an FMU that supports Co-Simulation in FMI version 2.0 or 3.0. Simulating an FMU with a variable step solver requires MATLAB® or MATLAB Runtime to be installed on the deployment machine.
Capture Simulation State, Fast Restart, and Step Through Model Containing FMU
Use the internal states of a standalone cosimulation FMU to enhance the simulation capability of a model with fixed-step solver FMU in Simulink®. Internal states of an FMU enables you to stop and resume simulation using model operating points, perform iterative simulation using fast restart, and analyze your model using backward simulation stepping.
Observe Internal Variables to Tune PID Controller Inside an FMU
In this system, the PID controller calculates the force that needs to be exerted on the mass to control its position. The Observer blocks allow you to tune the PID controller by providing wireless access to the control input and tracking errors that are configured as internal variables.
Export Simulink Model with Protected Model and FMU Import Block to Standalone FMU
Export a Simulink® model with external references to Standalone FMU. In this example, the model f14_flight_control demonstrates exporting protected model and FMU Import block to a Standalone FMU.
Export Simulink Model to Standalone FMU with User Specified Files and Archived Project with Harness Model
Export Simulink® component to standalone Co-Simulation FMU 3.0 with user specified documentation and harness model using Simulink Compiler™. This example demonstrate following features of Standalone FMU Export:
Deploy Simulink Model with FMU as Standalone Web App or Python Application
Demonstrates how to deploy a Simulink® model, which includes an FMU, as a web app or a Python® application for standalone simulation.
Export Network to FMU
