Mesh refining using sphere of influence
 

Dear all

I am trying to refine mesh around the estimated transition (LSB) location around the thick aerofoil -S814 for the low Reynolds number flow.

I had already created two spheres of influence as shown in the Figure attached, the element size are 0.00425 m and 0.00015 m for the bigger and smaller spheres.

On top of these two spheres, I want to add an addition small sphere as shown in Figure with 0.000075 m of element size....However, the CFX has shown nothing changed from the original mesh (the two spheres) with no error messages and a green tick after it finish meshing. The local min size is set below the element size of the sphere.....

Could anyone tell me how to solve this problem ?
Thanks
