[mesh manipulation] converging-diverging nozzle,o-grid

Rajshekar · November 24, 2010, 06:16

hi,
am working with ejector problem wherein primary and secondary nozzles are involved.
primary nozzle being converging-diverging nozzle(3d).queries regarding mesh generation for the same.
1. brief explanation of generating o-grid

2. can i do it without using stl file.if yes can u let me know the procedure of meshing CD nozzle with o-grid which snaps to the curvature of it.

3. links and must know info w.r.t to it
thanking you.

Hi Rajshekar,
I also work on cylindrical meshes using ogrid topology:

As a starting point have a look at these two links:
