Clicking the setup button is supposed to launch the vspaero executable
with the -setup option (and others).
If you run vspaero from the command line, it will dump out the available options
./vspaero
You can run './vspaero -setup filename' to get a default *.vspaero
file -- or you can specify things like OpenVSP does by running
'./vspaero -setup -sref 42.0 -bref 16.5 filename' etc.
filename is the name of the DegenGeom file -- but with the .csv dropped.
So, please try running -setup from the command line manually & let me
know if there are any errors.
Once the *.vspaero file exists, you should be able to run the solver &
viewer from the GUI as normal -- if that doesn't work, try them from
the command prompt as well.
