Hi,
I'm using SU2 version 8.0.0 and I want to run a case related to axial compressor passage, but unfortunately I'm receiving this error:

Did you mean TURBOMACHINERY_KIND?

Line 78 TURBO_PERF_KIND: invalid option name. Check current SU2 options in config_template.cfg.

I am not so familiar with the turbomachinery implementation so I hope somebody else will chime in, but this option was deprecated. Maybe have a look at the testcases/turbomachinery folder that we have, there might be a testcase that matches what you would like to do, maybe transonic_stator_2D?
