Fluent Meshing error
 

Hi, guys

I recently started to use Fluent meshing to generate poly-hexcore mesh.
I am using ONERA M6 wing as my model as shown in the following link:

Then I tried to 'Auto mesh' and choose 'scoped' for Grow prisms.
However, as soon as I select 'Set' button, I got this error.

I really don't know why it keeps showing up...

I imported the geometry model from the Design Model and generated tet- mesh first. Then, I tried to improve my skewness by saving tet-mesh model as 'Size field' and import CAD geometry again as 'CFD Surface Mesh' with 'Size field' that I saved before.

I know my explanation is it's hella confusion but i really need some help on this matter...

Please anyone who knows what to do or any advice will be gratefully appreciated.

Thank you guys.
