inflation layers for hexa mesh using icem cfd
 
Hi everyone!

I'm creating a mesh of a pipe using blocking and O-grid methods.I want to create inflation layers near the boundary layer but I can't do it using mesh prism command. Is it because I have hexa mesh or it is just because of the size parameters? Any suggestions? Thanks a lot, I'm quite new to icem cfd.

Regards, Apple

Hello,

Since you are doing hexa mesh, you can set the near wall node distance and the strech ratio in the O grid edge itself. This will help you in resolving the wall region well. I am not sure why you are trying for Prism option along with hexa. It is meant for resolving near wall for tetra mesh.

It's probably a good idea to go through some of the hexa meshing tutorials to see how to apply the edge parameters to get near-wall spacings for boundary layers and expand the mesh size into the interior.

Thanks Anantha and myron
 
Thanks guys, I usually use CFX Mesh before and I just started using ICEM. I'll follow your advice guys. Thanks!

ICEM tutorials
 
plz suggest some good tutorials for simple 3D geometry on ICEM that are available online.

i am not able to follow the tutorials given in ANSYS.
