  I am using Ansys Meshing to model my CFD problem and using CFX solver. I want to get minimum orthogonal angle 18 Degree in .out file. What minimum orthogonal quality I should maintain with my Ansys meshing file so that when it runs, it reflects an orthogonal angle of 16 deg in .out file..

  What is the orthogonal quality that you achieve in Ansys Meshing? If you have a orthogonal quality > 0.2, you should achieve the 18deg minimum orthogonal angle requirement of CFX.

  Sir..the mesh above has min orthogonal quality as 0.06 and still reaches orthogonal angle more than 18 degree. Seems your stated 0.2 value is over conservative and for general geometries, having moderate surface patch, reaching 0.2 orthogonal quality is tough. My belief is that, orthogonal angle is not only function of orthogonal quality, but also function of other parameters. Need your input..
