Downwash?

[Patrick Hammer]

Good morning,

Is it possible to extract the local downwash angle or velocity from OpenVSP? I know in MIT's AVL, they include it as an output in their stripforces calculation and I was wondering if something similar is available in OpenVSP.

Thanks,

Patrick

VSPAERO allows you to survey the flow field using an input to the *.vspaero file "NumberofSurveyPoints = N" where N is the number of points you want to specify.  For example:

NumberofSurveyPoints = N

1 x1 y1 z1

2 x2 y2 z2

...

N xn yn zn

This will output a *.SVY file with X, Y, Z, U, V, W.  https://groups.google.com/g/openvsp/c/8TF3DCy7BWA
