Dear Foamers,

I would like to run a 2D simulation for a wing-shape geometry, how could I do that with snappyhexmesh?

the refinement level will cut the background in 3D, how to allow it in 2D only?
and is that possible to refine a area, such as level 2, with refineMesh dict with automatic buffer layer generation?

Regards,
Yage

linnemann will become famous soon enough
Look at cfmesh instead for 2D

Picture taken from their userguide.
They also have tutorialfiles for making a 2D mesh.

Even better if the geo is simple make it a structured mesh using Salome.

Hi,
snappy is not a good idea for 2D, as you have pointed out, it refines in 3D allways.
The solution is to use blockMesh to generate 2D structured mesh (see:
http://www.openfoam.com/documentatio...#x25-1410005.3
and:
https://github.com/OpenFOAM/OpenFOAM...b2434eb3e2c4ed)
or you may try unstructured foamyQuadMesh. see tutorials in $FOAM_TUTORIALS/mesh/foamyQuadMesh

Happy foaming
Matej
