The FMI++ MATLAB Toolbox for Windows

The FMI++ MATLAB Toolbox for Windows

This toolbox for MATLAB provides the full functionality of the FMI++ library on Windows. This includes the import of FMUs for Model-Exchange and Co-Simulation as well as the export of MATLAB scripts as FMUs for Co-Simulation.

Instructions on installation and usage are given in the documentation, which is provided as part of the binary release version.

Features

• import of FMUs for Model Exchange (FMI 1.0 and FMI 2.0) into MATLAB scripts
• import of FMUs for Co-Simulation (FMI 1.0 and FMI 2.0) into MATLAB scripts
• export of MATLAB scripts as FMUs for Co-Simulation (FMI 1.0 and FMI 2.0)

matlab-fmu's Issues

Warning: FMI++ export interface is not active.

I was using it to generate the fmu model and it generated a warning. Does it affect the model negatively

`warning: FMI++ export interface is not active.

Loading of FMU dynamic link library (TestController.dll) failed!

When I import the exported FMU into Dymola for use, an error occurs during the simulation
The details are as follows:

Error: Integrator failed to start model.

... Error message from dymosim

ERROR: The simulation of ControlledRadiator FAILED

Variable has no start value

When I use the generated fmu model it produces an error (the variable has no start value). I looked at the function in createfmu and it does not seem to have a start value parameter defined
