The reason that I have chosen this cell size is that my particles in Rocky are 20mm so I need to have mesh size larger than particle size which I tried to satisfy that in hexa cells. Now , I want to ask in geometries like a mixing tank which we can not have a structured mesh and for example near the impeller we need a finer mesh , what should I do to have reliable results ? 

Thanks
