Dear all,

I am working on some turbomachine flows using SU2, now there is question about converting the multiple zone CGNS file from Numeca/IGG to *.su2 file. Anyone has ideal how to do this converting?

Thank you!

For multi-zone meshes, there are examples in the Testcases/fsi folder.
These are constructed from multiple single-zone meshes, with a format similar to those examples. Unfortunately this is not currently automated, but the format is fairly simple.

So, you would need to convert the single-zone meshes first, then combine them.
I'm not 100% certain of the proper boundary condition set-up for multiple fluid zones - I believe you will need to use the MARKER_INTERFACE boundary.

Thank you for your reply, Kline.

I will have try.
