It does not generate data

[Madalenita]

Hello, I want to learn how to use the program. I have downloaded the notebooks and it does not give me any error, but when doing the test with the examples, the system does not return data

this is the only thing it does.

It won't let me draw the mesh

This is because the notebook produces matplotlib plots that are not interactive (you can't pan, zoom, etc.). I use plain python without notebooks and it works well because the plots are interactive. There are some possibilities of having interactive plots in jupyter notebooks (using %matplotlib widget), but nothing for instance in google colab.
