Coefficients do not change in *.lod file when ref. area is changed

[Luís Filipe De Almeida E Silva]

Hi, everyone!

I'm running VSPAERO in OpenVSP 3.46.0. If I choose the wing ref. area or the horizontal tail ref. area the coefficients are almost the same in *.lod file. The same occurs at Load section of the exported *.csv file. But both files contain the correct ref. area that was chosen. That's weird.

Which ref. area is actually considered for loads?

Thanks in advance!

I'm not positive, but I think the coefficients in the *.lod file are sectional coefficients -- i.e. they are normalized by the local chord.

Thanks, Rob. I made a test using a simple rectangular wing and what you said seems to be correct.

Kind regards.

Luís.
