Problems with coedge curves and surfaces
 
Unfortunately I didn't notice that I was having this problem until I fully meshed my geometry and output to Fluent for simulation (where the mesh didn't load). When I open my file in ICEM, all of these problems appear in the dialog box. Does anyone have any suggestions on checks I could run through or ways to diagnose what exactly the problem is (or even to show me which curve is which so I know where the problem is)?

Code:

Hi Tom,


could you please explain how you solved your problem?


Best regards,


Lukas

Hello Tom,

Have you checked the mesh quality in ICEM (namely 2x2x2 and 3x3x3 Determinants)? ICEM can do many quality checks.

lukasf November 30, 2020 05:56

The mesh quality (at least for my case) was fine >0.5.



I was more interested in the error messages with respect to the geometry because the geometry seemed to be clean, too.

Hello Lukas,

Okay, understood. Is it an unstructured mesh? If so, maybe check that the edge - curve associations are all correct.

Edit: I realise this would be an issue when importing the model into Fluent.

Hi,

I am having a blockstructured mesh.


If you do not know ANSYS ICEM CFD, then I think it does not make sense to write in this post :)


My question more focused on what a coedge is and how to find out what edge and surface is associated with e.g. the id F_23123....

Hello Lukas,

I do know ICEM CFD, it is what I use for my research. It is Fluent I am not too familiar with.

Fair enough, I better understand what you are asking now. Hopefully someone who is more knowledgeable with Fluent can help.
