Surface names from Cubit (CFD BCs) not recognized in SU2 after CGNS export

Coreform Cubit Importing/Exporting
#1

Hello,

I’m currently working on CFD simulations using SU2 and encountered an issue with surface names not being recognized.

I generated a mesh using Cubit, assigned boundary names using CFD BCs, and exported the mesh in CGNS format. When loading the file in SU2, the mesh itself is imported correctly, but the named surfaces are not recognized.

I have attached the model with named surfaces and the command-line output during the CGNS export process.

Question:
Are there any additional steps or export settings required to ensure that surface names (defined via CFD BCs in Cubit) are correctly interpreted by SU2?

Any advice or insights would be greatly appreciated.
Thanks in advance! Hello,

Hello Shunya,

we currently don’t support writing the sideset name into the CGNS section.

We will log that as an enhancement request.

I will let you know as soon as we get this into a developer version.
