Hi CFD-online community,

I would like to seek some advice/help about meshing the geometry attached below. It is a cylindrical domain (single body) with ship propeller inside it that has been boolean subtracted away to model the flow domain of flow around a ship propeller in FLUENT.

I am using the patch conforming tetra method as the body is not sweepable and patch independent give me a warning message: "The number of unconnected mesh volumes differs from the number of bodies in that part.
". Just by changing the adv size function to proximity and curvature and relevance to medium, it gives me a max skewness mesh of 0.999... However, i believe this is not good for FLUENT as it seems fluent prefer a quality of at least 0.98. I have tried different sizing controls, virtual topology but to no avail.

I will upload a picture of the highly skewed elements later but they are mostly on the curved blades, hub and a few on the tip.

Would appreciate any advice here or it is ok for me to go ahead with a max skewness mesh of 0.999. will this affect convergence of my results in FLUENT?

Thank you.
