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.

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. |

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

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