[Archive] Cannot visualize results

Message by Alessandro Vicini:
I have this simulation which (at least apparently) runs fine, but when computation reaches 100% and I click on the “extract data and save project” button, after the “extracting time-depending data” progress window disappears, I am still in the simulation running and not in the data visualization window. So I can’t visualize results.
I have tried closing spis and re-running the case, and also changing simulation time and so on, but at the end of the computation I still have this strange behaviour.
What could be the issue?
