Fluid dynamics 101!yeeees Aidan is one of the best teachers I have seen! Specially considering that is finite volume method.... Something not simple at all... Looking forward! Put this guy with Tobias and you get the dream team of cfd 😂!
Haha I have had the same situation with meshing. I always thought "I am from a free software generation" and I lost a lot of time trying to understand how these meshing tools work, but I want to say now, do not do it. Just make your mesh with ICEM if your Uni has license on ANSYS and go in paralell trying to construct the same mesh on free software. But don not stop your project on that. Learn it sequantially. Incredible Podcast.
Have a look at my second channel „Jousef Murad LITE“ where I posted clips from Aidan exactly tackling those questions. For books, I have a video on my channel for my top 3.
