Hello everyone, I've been running NACA0021 simulations with the SST model but wanted to investigate how the k epsilon would differ.

When I ran the k epsilon simulation with a reynolds number of 50000, simpleFoam crashed with the [2] #0 Foam::error:rintStack(Foam::Ostream&) at ??:? message. I double checked to see if my boundary conditions made sense and to the extent of my understanding they do, so I'm stuck in that regard.

However, with a reynolds number of 1e6, there are no crashes and simpleFoam reaches convergence at some angles of attack. Can someone look at my files to make sure I'm not doing something horribly wrong?

My Re50000:

Thanks in advance,
