Mesh generating for an annular ring
 
1 Attachment(s)
Hi all;
I am investigating the flow into an annular ring. The r and Z components as well as boundary conditions have been specified in the attached picture.
Briefly, the boundary conditions are inlet, outlet and adiabatic(insulated) walls. Really, the geometry is 3D but since the flow & geometry are axisymmetric, they have been presented as 2D in attached file.
How can I generate mesh for this geometry?
Do I have to use wedge type in blockmesh or to generate the mesh by other mesh generator programs such as Gambit and exporting it to blockmesh and paraview?
What's the real solution?
Thanks a lot for any suggested solution.

With the following commands you find all tutorials using a wedge geometry:
Code:
cd $FOAM_TUTORIALS
find . -iname "0*" -type d | while read d ; do grep -ri wedge $d ; done
This one sounds promising: ./multiphase/interFoam/les/nozzleFlow2D/
Code:
mkdir -p $FOAM_RUN
cd $FOAM_RUN
cp  -r /multiphase/interFoam/les/nozzleFlow2D/ .
cd nozzleFlow2D
blockMesh
touch test.foam
Got to parafoam / paraview and check the created mesh. This should be a good starting point for you.

Dear jherb;
Nozzelflow2D isn't same my case.
For me, the geometry is such as a ring (semi-wedge) according to the new attachment.
Is there the idea for my geometry meshing?

Hi I would use www.salome-platform.org

Very easy to define geometry and mesh.
