is it right:?
1:run blockMesh
2:snappyhexMeshDict -overwite
3:extrudeMesh

Sandy,
Dear nimasam,
Could you please help me with something.. I am trying to do simulation for a swirl atomization with OF 2.1.1, interFoam solver. My geometry is like in the attached picture, I want to use blockMesh to construct the mesh but I have a problem in defining the internal walls for the mixing region.
Sandy,

yep its right
1- blockMesh
make your base mesh
2- snappyHesMesh -overwrite
extract your airfoil in it

3- extrudeMesh
you can derive one cell thick geometry

dear sandy i suggest to use snappyHexMesh, you can create your mesh in a CAD software, then easily with snappyHexMesh you can mesh your geometry

Dear nimasam,
Thank you for your advice. So as you suggested there is no way to use blockMesh and the only way is CAD and snappy . It is impossible or possible but very difficult by blockMesh?

i guess its possible, you should define several blocks, but it would not be easy tasks and you need to be patient enough

Thank you so much, I will try to do it by blockMesh, can I ask you If I stuck or had a problem in it?
