FFD_SURFACE_POINTS not created after SU2_DEF

[flybob91]

Dear SU2 developers,

I'm trying to set up a FFD box however, after having run the SU2_DEF command, I noticed that no FFD_SURFACE_POINTS are crated in the mesh_out.su2 file. I tried this successfully with SU2 v7 but repeating the same procedure with SU2 v5 lead to the problem. What can be the cause of such a problem? Is the procedure to create the FFD box the same between SU2 v7 and v5?

I tested the following .cfg file with the mesh mesh_NACA0012_inv.su2 and it's not working

Hi @flybob91 ,
I unfortunately cannot help you with fixing things from v5 and to be honest there is not much support for legacy versions. Whatever makes you use v5, it might be a better way to bring that to the current version. The community is always happy to support bringing back old features or redesigning them for the current develop. So if you interested in that, feel free to let me know.

Cheers, Tobi
