Hi


You are correct, doing it this way for you case breaks the face mesh when it is projected when it has boundary layers. Without BL it works fine.


There is a way to do it using the "Extrusion 3D" meshing strategy.


Here is a link to the case and the checkMesh output.

Checking geometry... 
    Overall domain bounding box (0 -49.9013 -49.6057) (700 49.9013 50) 
    Mesh has 3 geometric (non-empty/wedge) directions (1 1 1) 
    Mesh has 3 solution (non-empty) directions (1 1 1) 
    Boundary openness (7.93909e-17 3.36127e-18 -1.20437e-17) OK. 
    Max cell openness = 7.47279e-16 OK. 
    Max aspect ratio = 46.4566 OK. 
    Minimum face area = 1.33659. Maximum face area = 316.204.  Face area magnitudes OK. 
    Min volume = 8.42164. Max volume = 973.656.  Total volume = 3.36768e+06.  Cell volumes OK. 
    Mesh non-orthogonality Max: 19.7951 average: 7.36319 
    Non-orthogonality check OK. 
    Face pyramids OK. 
    Max skewness = 0.315532 OK. 
    Coupled point location match (average 0) OK. 

Mesh OK.
