SnappyHexMesh on convex surfaces
 
Hey Forum,
im trying to build a inflate boundary layer in my CFD model, to calculate the turbulence correctly.



I use SimScale with SnappyHexMesh.


On flat surfaces the infalte boundary layer was created very good and looks proper, but on concave surfaces the layer collaps suddenly, and came back from the surface.


Did you have any experince with concave surfaces with an inflate boundary layer and SnappyHexMesh ?

Best

regards
