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 to a friend of mine, so here I am.

Just installed it, and I'm completely lost, as expected. From what I've been reading, it seems that I need to get familiar with ''the Shell'' at first, so that's what I'm doing.

I want to know if this step is necessary, because I feel this is going to take a great amount of effort. Don't get me wrong, I'm more than willing to invest my time on this, I'm just afraid this effort could be put to better use.

Thanks so much in advance!
