Depends on your meshing method - ANSYS Meshing in WB, Fluent meshing, ICEM/CFD Hexa or Tet/Prism, Pointwise meshing, Gambit, mesh import from NUMECA,......?

@thomas frank will you please elaborate about mesh refinement in ANSYS FLUENT. I would also like to know about fmg initialization and what's your recommended method for initialization?
Md.Wasi Uddin What I have tried and tested is that, if you have a complex geometry ofcourse i had, and i had not the expertise to do structured meshing in ICEM CFD. so choose tetrahedron meshing which is i think by default in most the cases, smoothing=high, relevance centre=fine, and set relevance to 100% this is 0 by default, and furthermore if you have used inflation always do edge sizing to maintain the aspect ratio and skewness. this is one way. dont worry about the elements, elements count would be huge, but your quality would improve. the second way to use proximity and curvature which will increase the number of elements and ofcourse the mesh quality, atleast this one worked for me. third way is to improve in fluent via command. make sure defeaturing is off which is off by default you can also try make the elements quadratic from linear.
