Retrieving CL_max from T1 Analysis result file.

João HackbartJoão Hackbart asked 2 years ago

I’m doing performance calculations on a series of designs that were generated through the scripting workflow.
Currently I believe there is no straightforward way to retrieve the CL_max of an airplane. The current steps are, running a Type 1 Analysis and then looking for the highest CL value from the csv table.
However, that is not ideal for automating because each airplane might have a different amount of angles of attack that were calculated, and therefore the actual text location of the CL_max is always different.
 
Would it be viable to implement a field in the result csv file just for the CL_max of the Type 1 Analysis?
 
Thank you!

Hi João,
Technically it could be done, however I am reluctant to change the file format now that other users have written scripts to use the existing structure.
Also CL_max as calculated in panel methods isn’t a reliable value because stall effects are not taken into account.

Hey André,
Thank you for the reply, I’ll stick with the CL approximations, which as you describe are likely more accurate than the panel method.
