 February 13, 2012, 00:20 Simple meshing problem in ICEM #1 New Member   fkh Join Date: Sep 2010 Posts: 6 Rep Power: 8 Sponsored Links Hi All, I'm a beginner in ICEM and Fluent. I am currently having a problem with the meshing in ICEM. I have created an internal surface inside a domain puerly as a calculation surface (not intend to influence the flow inside the domain). However, when I am creating the meshes for the domain, the meshes have filled out the whole domain and for every boundaries except this internal surface. There are no particular meshes generated for this internal surface, and later when I import the domain into Fluent, this internal surface is even missing. Can anyone please give me some hints or advices to solve this problem please? Thank you very much. Regards, FKH

If it is just a virtual surface, you do not need to creat it, just get variables in a plane which could be generated in the CFX Post.

If you do want an internal block face to project to a surface and generate shell elements, you can just go into the blocking => Associate DEZ and associate face to surface... __________________ ----------------------------------------- Please help guide development at ANSYS by filling in these surveys Public ANSYS ICEM CFD Users Survey This second one is more general (Gambit, TGrid and ANSYS Meshing users welcome)...
