Hello David,
thanks a lot for the information.
I was thinking I should do the conversion and indeed you confirmed it.
The main reason I am meshing locally is that I would like to check the results I am obtaining in Fluent with the ones I can achieve in OpenFOAM, therefore I would like to have a cross-check without any influence of different meshes.
Cylinder seems to be an humble object but in reality simulations have quite many issues:)
Have a nice day and thanks again for the help.
Fabio
