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

is it right?
1:run blockMesh
2:run snappyHexMeshDict -overwrite
3:run extrudeMesh

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,

Hi nimasam,
this is my geometry

Sandy,

Hi
i saw your test case, good job ;), whats the problem?
its 2D now and there are several layers around airfoil.

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 guess, you need to make a public link in dropBox, then i would access your link ;)
now i can not see any thing :)

Dear nimasam,
I am sorry, this the link again and hope it is working

Sandy,

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

blockMesh
 

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?
Sandy,

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

blockMesh
 

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?
Sandy,

you can post your problems here, forum users will try to help you :D

Try this...it should work
 

In snappHexMeshDict, do not forget to add this part otherwise snappyHexMesh will work but still layers wont be added.

features
(
{
file "yourcase.eMesh";
level yourinput;
}
);

Example:

features
(
{
file "motorbike.eMesh";
level 6;
}
);

The thread is too old still posting if someone got stuck like I was due to this.
Hope it helps
Thank you !
