I am a new SU2 user and needed to know how the mesh dimensions can be scaled up or down in order to have different chord lengths with the same mesh geometry because we want to use the mesh with unit airfoil chord and specify it as 15 cm actually. Also, what purpose do the reference parameters serve, like reference length and area?Do they act as scaling parameters?
Thank you.

regards,
AASHA

Hi,

To scale the mesh dimensions just include these lines in your cfg and then run it through SU2_DEF.


DV_KIND= SCALE_GRID
DV_MARKER= ( tags of your mesh )
DV_PARAM= ( 1.0 )
DV_VALUE = scale factor you want



The other question you ask, about the reference parameters, I don't know. I'm also relatively new to SU2 and still trying to figure things out. If you find out I would be interested in knowing their function.



I hope i was at least a bit useful.
Best regards,
Dylan
