Different results compared to hands-on document using MUIO V5.4

OSeMOSYS

Firstly, thank you for updating MUIO v.5.4. It took us a while to fully installed.

After following the hands-on documents from the Climate Compatible Growth programme, I found out that results differ from the graph on the Hands-on 6 from the year 2026 and afterwards. And even with different performance compared to the graph on the Hands-on 8.

Therefore, my questions are 1) whether it updates equitions or default parameters in the latest MUIO when compared to MUIO v.5.0.0? 2) do I miss something in the data preperation OSeH08?

Thank you in advance!

Dear @Vicki, There were a couple of changes in the code, but they should not create any differences for a simple exercise like this one. I would recommend repeating the exercise and taking care when transferring the input data.

I have this too. Try to install the older version, but didn’t work. Try to rebuild the model from scratch like many times, the result is still the same. I think there is a fundamental changes in the v5.4. that should be adjusted, to reflect the version of the exercise (v5.0). Or maybe the hands on exercise need to be updated to reflect the newer version of the app. Now i don’t know, should I continue learn this or not, or find a newer and more relevant one.

Dear Fernando,

Thank you for looking into this. After several days of trying, I was still facing the same issue, which has been quite frustrating.

Fortunately, my learning progress finally moved forward after two specific steps:

  1. ignoring my previous errors from Hands‑on 7, and

  2. following the most recent YouTube tutorial.

My reflections are the following:

  1. When the input data is clear and correct (as in “Tutorial to Create a Basic OSeMOSYS Model Using MUIO”), working with MUIO v5.4 becomes much smoother. This allows me to focus on the critical aspects of system optimization rather than troubleshooting basic model issues.

  2. After reaching Hands‑on 13, I realized that some of the errors came from missing or incorrect inputs in the data preparation for Hands‑on 7. For example, the parameter “TAnnualMaxCapInv” was missing.

As a beginner with this tool, I do not yet have the full capacity to calibrate all datasets on my own. I would therefore be grateful if you could review the data preparation files on your side and update them as needed using MUIO v5.4.

Thank you in advance for your support.

Yes, I totally agree with you on this. However, I still encourage you keep going with this.
