XFoil_Worker: extend max. number of characters for command-line arguments

[Matthias231]

Please extend the maximum possible number of characters per argument from 80 (?) to 255. This will be necessary for call of XFoil_worker from strak_machineV2.py

... this is crazy! ;-) Is it because of subdirectories? Better have an additional arugment to set a (working) directory?

[Matthias231]

Yes, that's exactly the reason.

Yes, an additional argument to set a working directory would be a good idea and also would solve other potential problems.

In my case it would completely solve the problem, but the working-directory in my special case needs 77 characters and so is very close to the limit.

So I if it is possible to implement an additional argument with more that 80 characters I would suggest to use 255 characters to have some space for the future

ok! Which option should use this working directory? -i input file -a airfoil -o output file prefix The polars are already generated in the subdirectory

_polars. Would it be "doppel gemoppelt" ;-) ?

Hi,

• I would suggest to use the working directory for all the options, so everything is read / created automatically inside the working directory. Just as if XFoil_worker.exe would have been started inside the working directory.

• It should still be possible / tolerated to prepend a further sub-directory to the options, just as it is implemented at the moment (no change). So e.g. the option -i /ressources/myInputs.txt should still be possible and will read "myInputs.txt" from subfolder "ressources" inside the working directory

• Generating the polars: I think generating the polars inside a subdirectory inside the working directory is o.k. (no change)

Hi, just pulled the repo, works fine now!

[jxjo]

.. I'll close this issue. Let's see if we still need the working dir.
