There are some awesome simulations in the SimScale project library. Though I am quite fond of anything involving fluid flows, the one simulation I liked most so far is the structural dynamic analysis of a [deep drawing process][1].
Just take a look at this [video][2] and think: “Is it not simply awesome that those kind of things can now be simulated in a web browser?”
My colleague Ali just published a new library project: A compressible flow analysis of a centrifugal compressor. That’s the first library project showing a compressible flow simulation including a rotating zone - pretty neat! Here you can read more about it:
