• 👋 Hi, I’m @janpeter19

• 👀 I’m interested in Modelica and especially biotechnical applications, see paper.

• 🌱 I’m currently learning how to reach out more using Google Colab. I have prepared several examples for you starting with the repository BPL_TEST2_Batch. Here you follow a Jupyter notebook and can continue interact using Python and modifiy the simulations and graphs shown. More about the technology used here and about the modelling here. No installation needed!

  Google Colab major announcements and the technical release-notes.

Note 2026-09-23 I just became aware of that Colab VM now runs by default Ubuntu 24.04.5 LTS. The upgrade have likely been made earlier in September. So far, I have not seen any problems due to this upgrade. The FMUs are made in an Ubuntu 22.04.5 LTS environment but re-compilation seems not needed.

Note 2026-09-21 Now FMU_explore version 1.2.4 is released. It is a maintenance release with focus on code improvements. The applications will be updated with this version of the package as default during the days to come.

Note 2026-09-14 Today FMU_explore version 1.2.0 is released! This means that the version is addressed slightly differently from before, see the notebooks. The application BPL_TEST2_Batch can be run with both pyfmi and fmpy using this released version. The other applications will gradually in the coming days be updated in a similar way.

Note 2026-08-21 The setup-scripts for each application have for a long time had a structure of a specific application part and a general part that I call FMU_explore. Now this general part is imported as a separate module file and placed at a central place. This organisation facilitates future maintenance and further development. The setup files are now two smaller files and the setup takes up a few lines in the notebook for clarity. Now for test just for the application BPL_TEST2_Batch. The module is done for PyFMI and will later be done also for FMPy. The version is 1.1.0 and have otherwise the same functionality as before. The ideas behind FMU_explore you find here.

Earlier notes you find here.

• 💞️ I’m looking forward to collaborate on expanding the examples of use of Modelica in Colab. I also tailor-make models of biotechnical processes for your needs on a consultancy basis. Work with processes involves broader data analysis and is a part of my work, and simulation is just one tool, but an important one. Digital Twins is a catchword these days and part of what I do.
