Hello everyone,

In previous versions of OpenVSP (e.g., v3.44.5), the *.lod file contained a section that reported aerodynamic loads for each surface separately, such as cumulative CL and CMy, typically listed as a function of wake-sheet .

In the newer versions, the *.lod files seem to include only the total loads for the entire configuration, and I can no longer find the per-surface load breakdown.

Is there another output file or option in the current versions of OpenVSP where the per-surface loads are available?
Or has this feature been removed, meaning that the only way to obtain surface-wise loads is to manually integrate the sectional and distributions over each surface?

Any guidance would be appreciated. Thank you!

I will mention this to the developer.

Please do Rob. I have developed a suite of python apps for FAR 23 loads that depend on the pre-v3.45 *.lod info. Without it I am stuck with v3.44.5 for a long time.
