FMU Importing

Use a functional mockup unit (FMU) block to bring third-party functionality into Simulink^®

The FMU block lets you import your applications, contained in FMUs, into Simulink. This block has two modes to integrate FMUs that implement:

An FMI co-simulation interface. These FMUs contain local solvers.
An FMI model exchange interface. These FMUs do not contain local solvers.

Blocks

FMU	Include Functional Mockup Unit (FMU) in model

Functions

`fmudialog.compileFMUSources`	Generate binary for FMU with source code on current platform (Since R2024a)
`fmudialog.createBusType`	Create all FMU bus objects required for structured input or output ports in workspace (Since R2020b)
`fmudialog.createEnumType`	Generate all enumeration classes required for FMU input or output ports (Since R2020b)
`fmudialog.createTypeObject`	Generates enumeration and bus objects required for FMU input or output ports (Since R2020b)

Featured Examples

Import Co-Simulation FMU into Simulink

Use the FMU Import block to load an FMU file. The FMU file supports execution in co-simulation mode. Simulink® software supports stepping back and forth, tuning parameters in between, and saving states for the FMU Import block as long as the FMU itself supports these features.

Import and Simulate FMU with Time-Based Clocks in Simulink

Demonstrates the use of a Functional Mockup Unit (FMU) containing time-based clocks in Simulink®. You can import standalone co-simulation FMUs that implement the following types of time-based clocks as defined in the FMI 3.0 standard:

Simulate FMU with Enum Type Ports using FMU Import Block

The example demonstrates how to use the FMU import block to simulate FMUs that have enumerated data type ports. The FMU import block enables the import of functional mockup units (FMUs) in Simulink.

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.
