Hello everyone! I am a mechanical engineering student from Brazil, and I'm trying to get into numerical simulation in fluid dynamics.
A teacher recommended OpenFoam and from what I've been reading, it seems that I need to get familiar with ''the Shell'' at first, and this is why I'm here. I just started using Linux, so I'm kinda lost. I would like to know if you guys recommend any book or material for getting started, and on what I should focus on the beginning. Sometimes, especially during the initial phase, newbies can get dizzy from all the overwhelming information.
Thank you so much in advance!
TL;DR Where to get started learning the shell and what should I focus on
