high skewness cuz of bad mesh at trailing edge NACA0012
 

Hallo,

https://drive.google.com/file/d/1meR...ew?usp=sharing

as you can see, there is a little bit problem cuz of weird layer at the trailing edge of NACA0012.

Has anyone Idea for the solution?

Max. internal face Skewness is about 8.

Hi!


First of all if you visualize your mesh turn the "decompose polyhedra" off in paraView, and in the silces turn the triangulation off also, and you will see the mesh. What you see now is a triangulated mesh, not the real one. In reality it is not that weird, however the boundary layer will collapse there since the mesh would have really poor quality. You can try to refine the trailing edge more, but layering is not an easy to use and trivial feature in snappy.

Thank you for your tip!
