I have a mesh created by Icem for a model rotationally periodic of 22.5 degs.
I want to create periodic replications of the model, to extend it to 90 degs, but I would like to avoid Icem as the blcoking is pretty awful. I read about this Tmerge utility and decided to have a go. It creates the mesh, but then it leaves some internal faces left as walls. When I open with Fluent (I do, because I want to re-apply periodic bc using the make periodic command), I cannot convert these walls to interior, nor I can get rid of them. So I tried to re-import the newly created mesh in Icem, define these surfaces as interior, and the re-open with Fluent. Fluent gives me a message "Unable to convert to interior. Only one adjacent cell thread". I understand the problem of one adjacent cell thread but I would expect this to be sorted by the Tmerge utility. Otherways ... what's the point of using it? Anyway, can anyone tell me how to handle this situation? How can I get rid of these internal surfaces within Fluent? Many thanks Dario |

I have somehow the problem you encounter , I mesh one quarter of my domain in icem which is a circle , then copy by rotation the geometry and blocks , but when I import it to fluent, It fails to change some boundaries that I defined as interior, and they are changed to wall type.
I hope any of expert could give us guides through good approach. |

Hi
a couple of weeks ago I had the exact same problem as you two. As I couln't find any satisfactory solution for my specific problem I ended up converting my mesh to openfoam (fluent3dmeshtofoam) to use the utilitys 'mergeMeshes' and 'stitchMeshes'. After that you can reconvert your foam mesh back (foamMeshtofluent) I got the hint somewhere around this forum, simply search for 'tmerge' and you will find the post. |
