Changing boundary faces to interior faces
Posted: Sun Apr 11, 2021 9:12 pm
Hi,
I am using ICEM CFD for mesh generation exporting it to Code_Saturne 6.0.5 via CGNS. I have constructed a quarter model of the domain and used ICEM to mirror the mesh in two directions to create the full domain. Necessarily the surfaces on the interface between the mirrored components contained boundary faces prior to the mirroring however this should no longer be the case after mirroring. The listing file indicates that there are still some boundary faces which means that the simulations are crashing as there are undefined boundary faces.
I was wondering whether these faces can be forced to become interior faces, it would also be useful to understand how Code_Saturne determines something to be a boundary face and whether this error is indicative of a 'hole' in the mesh due to the mirroring process. I have attached some images and the listing file. The images show the geometry and the post-processed boundary faces with the additional boundary faces. I also added an initial user subroutine written to try and force the faces to interior faces, although it was speculative, and it hasn't worked (it compiled fine and crashed in the same way).
Thanks in advance,
Matthew Falcone
