Hexahedral mesh problem (?) regarding flow past I-beam

Hello everyone, I'm simulating a 2D flow past a I-beam using k-omega SST turbulence model and I'm having some trouble with the mesh (I guess). I've managed to get a solution with periodic vortex...

Why do calculations blow up when using finer grids (k-omega SST)?

Greetings again, I'm simulating the flow past a I-beam using k-omega SST turbulence model. I could get the solutions for grids with max y+ of 60, 50 and 40. However, when I simulate with y+ 30 or...
