Quad Meshing on Surface
 

Using DM in Ansys and trying to mesh a turbine blade with a rotating boundary. Inflatiojn layer and boundaries and the mesh looks good but cant seem to get the surfaces of the blade to mesh using quad cells rather than tets. I want quads near the surface which will move out to a tet mesh further out. At present its meshing with tets at the near wall region for the blades and this is resulting in more cells needed. If I can use quads for blade surface it will half the cells needed in the near wall region which is good.

Its probably a simple fix but some help would be very much appreciated from a newbie to these forums but have used their help a bit in the past.

Attached pic of surface mesh at present.
