question about mesh features

happy · April 29, 2012, 23:08

I conduct my mesh by CFX usingfluent as solver preference and the features were okay to me by viewing it by CFX mesher but when I write file to show its Diagnostics by ICEM CFD software, I found that there is some problems. Howevever I misunderstand it yet. So can any one tell me what does mean that
2060 problems were found for 3_surface_node_internal_faces
The ICEM CFD provide me with the following table
Diagnostics Check:

Diagnostics Number of Elements duplicate 0 multiple 0 triangle_box 0 single_2 0 single_multiple 0 standalone 0 single 0 delaunay 18 overlap 0 3_surface_node_internal_faces 2060 uncovered 0 missing_internal 0 nmanvert 0 disconnected_vert 0 vol_orient 0 surf_orient 0 hanging 0 penetrating 0 disconnbars 0
quality is from 0.180604 to 0.999911.
any input can help and thanks in advance.
Regards

The explanation of all these errors is in the ICEM documentation. You will need to access it from ICEM, it is not part of the normal ANSYS help.

thanks for your comment I found that 3-surface-node-inernal-faces has big bad impact on my mesh. However, I did noy understand what the a mean to start improving of my mesh. i went through the documentation but there is no any comment6 about 3-surface-node-inernal-faces. did you? Could any one help me more about the meaning of 3-surface-node-inernal-faces? Any input can help, please.
See attachment please

I do not have ICEM so cannot check. I recall ICEM mesh checks return mesh errors (ie the mesh will not work with this error) and mesh warnings (ie the mesh will run, but may have convergence or other issues).

Is this an error or a warning? If it is a warning and you don't know what it is or how to fix it then just proceed anyway, and if it is a problem it will become obvious (hopefully) when you do the simulation.

If you can send me the ICEM file and I will fix your problem.

Please use .rar or other softaware to compress your files

I basically use CFX software, and I used the ICEM only to check the features of my mesh. So how U will fix my mesh(by icem or cfx?)?
pls reply ASAP.

through the report produced by ICEM I got the following;

2268 problems were found for 3_surface_node_internal_faces
so what U think, I have already convergence issue!!

I will use ICEM, CFX mesh is good for some meshes and for some easy domains. For the rest I use ICEM.

Sorry, one question, which is the porpuse of it? academic porpuse or something related with your work.
I have benn a litle busy because I am finishing my master degree thesys and as you can imaging I am veeerry busy.
But no porblem I will work in your mesh today!!! I `ll try to send it to you today or tomorrow...

Dear Safia, I started to work with your case topday but I couldn´t open your file, I think it is because I use winrar.
Could you compress your file in .rar extension ....
Best Regards Julio M
