MATLAB: Do I need a Simulink license to run an FMU generated by exporting a Simulink model in R2018b

simulink

Hello, I was writing to ask a question about the FMU add-on in R2018b.

Is a FMU generated by Simulink supposed to have any dependencies on Simulink?

When we generated a FMU and tried to run it on a machine without Simulink, it was not loading the dll because of some dependencies on MATLAB.

After downloading the MATLAB Runtime on to the machine without MATLAB we resolved all the dependencies except:

– libMatlabEngine.dll

Does someone need a MATLAB and Simulink license to run an FMU? Or is having the MATLAB Runtime enough to run an FMU?

Best Answer

Yes, to run an FMU generated by Simulink requires an active license and a local installation of MATLAB and Simulink.

When a third-party tool runs the FMU, it checks out required licenses and starts a local installation of Simulink to start the model.

Please follow the following documentation link for more information:

MATLAB: Am I unable to import an FMU after exporting it from a Simulink project

The issue is that there is not an available MATLAB session to run the co-simulation.These are the steps to resolve the issue:

1) Open a new instance of MATLAB.

2) Execute the following command in the MATLAB command window of the new MATLAB instance:

>> shareMATLABForFMUCoSim

Note: please do not run anything else in this new instance of MATLAB.

3) After importing the FMU in the first instance of MATLAB, run the model.

MATLAB: Importing legacy models from created with MIT Toolbox

Yes, the models created and which were working with MIT Toolbox can be used with the Simulink Support package for PARROT Minidrones, provided they follow the steps below:

1. Update the existing model to be used with Buses and 4 ports. It is mandatory to have the these 4 ports and signals through them as specified below:

Specifications of root level ports and signals through them

* Sl. No Port Type Data Type Storage class for signal through it Size Alias

*1. Inport (AC cmd) Bus: CommandBus ExportedGlobal NA Cmd_inport

* *2. Inport (Sensors) Bus: SensorsBus ExportedGlobal NA sensor_inport

* *3. Outport (Actuators) double ExportedGlobal 4 motors_outport

* *4. Outport (Flag) Uint8 ExportedGlobal 1 flag_outport

2. You can copy paste the controller logic from the old model and update the signals in such a way that the above criteria are met.

3. If simulation works and is successful, proceed to build the model.
