Having trouble meshing nozzle

shang2 · November 18, 2018, 13:56

Hi,

I am having trouble meshing a nozzle that I drew in Solidworks. It is not axis-symmetric. I would prefer a structured mesh, with points piled near the wall, but at this point, any mesh would be good. I will be using the mesh in OpenFOAM.

The link below contains the Original Solidworks file as well as .step and .igs exports.

Thanks in advance!

Please provide more information including:

Read this post.
Which version of Pointwise are you using?
Which gridding techniques have you already tried without success?

Since your case is NOT axisymmetric, you will need to use surface quilting, and extrusion techniques to build boundary layers and also set extrusion boundary conditions on the symmetry walls.
