Dear Mr. Reber!

Thanks for your ultra-quick answer. 

Yes, everything is done inside the container. That's why it is so convenient for me... :-)

I will digest your answer and do some more digging. 

However, this is the container: https://github.com/tianyikillua/code_aster_on_docker
It is really high performance stuff, well executed by tianyikillua. 

Kind regards,

Mario.
