Hello Jose It all depends on the mesh itself and particularly on the mesh near the cylinder wall. Have you used an inflation layer? What’s the orthogonal quality and aspect ratio? Whats the skewness etc... In the other hand you need to look at the type of mesh is it hexahedral or tetrahedral (the first one is convergence-friendly) and last but not least you need to be aware that some flow behaviour are transient in nature and you would find some difficulties solving them through a steady state model.
