Hello Rob
increasing number of cells further from 12 to 18, Y+ improved more globally along length of ship, but not in local regions, how i use split ratio for local region, i didn't understand definition of guide book about split ratio,if you could explain it please in simple words(which base face they talking about).
i also want know, i want throw this model mesh once i get y+ below 300 in optimization tool, probably as my optimization is multi constraint, Gradient based optimization will be better for my case, i want optimize my geometry mesh by reducing drag or ship resistance...is there is issue if i refine with anisotropic adaption & later using optimization tool??? Are optimization inbuilt tool of Ansys are compatible with Highly refined mesh??(like that of with the help of anisotropic adaption??
