Hi there
My apologies for my english
I am trying calculate a NACA0012 with simpleFoam. I maked two differents 3D mesh, the first one is a mesh non structured with SnappyHexMesh and the second is a structured mesh with pointwise, in both cases the checkMesh is ok and the boundary conditions are the same. The number of elements are similar.
AoA 5degrees
V=10 m/sg
Fluid air
The results with non structured mesh for NACA0012 are Cl= 0.406(this value is ok) and Cd=0.021 (this value is too high)....the solution find converge
But with structured mesh THE solution dont find the converge
Attached you can find folder 0 system and pictures...anybody can I help me?
Thanks in advanced
Simón
