How to use

1. Download the pre-built executables from the latest release
2. Validate an FMU: fmusim validate my_model.fmu
3. Simulate an FMU: fmusim simujlate my_model.fmu

FMU Check

A free web app to validate FMUs online. It's powered by FMPy (currently v0.3.21), hosted by the Modelica Association, and performs static checks only (i.e. no simulation of the FMUs).

How to use

1. Go to fmu-check.herokuapp.com
2. Upload your FMU file
3. Review the validation results

You can also deploy FMU Check locally using FMPy's built-in web app:

python -m fmpy.webapp my_model.fmu

Validate your FMU

FMPy

A Python package to simulate and validate FMUs that has a graphical and a command line interface and

• supports FMI 1.0, 2.0, and 3.0
• supports Co-Simulation and Model Exchange
• runs on Windows, Linux and macOS
• compiles C code FMUs and generates CMake projects for debugging

How to use

1. Install FMPy: python -m pip install fmpy[complete]
2. Get info about an FMU: fmpy info my_model.fmu
3. Simulate an FMU: fmpy simulate my_model.fmu
4. Open the graphical user interface: python -m fmpy.gui
