Hello dear forumers
Greetings!

AFter completing the 2D validation of NACA0012 I now move to validate 3D Onera M6. I take following guidelines for my study:

I download the stp file for wing and create the tunnel around it. PLease bare in mind I am now just meshign the wing with perfect hex and hence I keep the tunnel size small until I am happy about the mesh and blocking methods. Once I am ok with the blocking, i replace the geometry with bigger dimain (30 chord length to all 3 sides) and then associate edge to curve. This is I do because so I dont have to zoom in and zoom out while deciding on the blcoking. The final mesh will also has Y+ values close to 1 so to resolve the boundary layer and gradual increase from wall to domain boundaries. I will do some transonic simulation too so I will make sure the mesh is fine to capture the bow shock and trailing edge shock.

PLease have a look my mesh so far:













Any advise on whether I need to change the blocking method? I see dome shape inlet in many case studies but it is hard to block so I choose simple rectangle tunnel.

THank you for all the suggesion, this form is very helping
