Flow field vectors on wake/behind wing/Treftz plane

[José Roberto Clark Reis]

Hi all!

On VSP aeros postprocessor, I have been able to show the vectors of the flow field in a certain cut plane, similiar to a Treftz plane. My idea now is to apply Lagrangian particle tracking and try to optimize the spray bar. For that, I need to "queue" vsp aero to obtain the values related to these vectors in a certain cut plane. Any ideas? Is there any file or inner structures of the code where this data is stored?

Cheers, José

Jose,

You can specify a set of velocity survey points in the *.vspaero setup file.  The GUI won't do it for you, but you can set up a case in the GUI, edit the file manually, then run it at the command line.

You need to add list of survey points to the bottom of the file.

NumberofSurveyPoints = N

1 x1 y1 z1

2 x2 y2 z2

...

N xN yN zN

VSPAERO will create a *.svy file with the x,y,z,u,v,w data for each point in your survey.
