why is everything wrapped in BCS? #51

Closed mayork closed 7 years ago

1ozturkbe commented 7 years ago

Because the codes will not converge without it, even though there are zero variables hitting the bounds. Still under investigation...

This is related to issue #52, and when that gets resolved should be a non-issue. Allowing lower reltol allowed for the removal of BCS. Will keep this open so that we make sure to remove Bounded.

Another reminder to keep this in the foreground...

@mayork I don't like that we still use BCS, but this is only because we have sizing constraints (like climb time, climb distance, VT yaw rate) that are sometimes not active. Should we close, since we will likely never be able to get rid of BCS?

mayork commented 7 years ago

yes close...if you look at the output all that is at the bounds is either inactive tail sizing constraints or other inactive variables (like min cruise altitude if that isn't subbed in).

I'm closing now.
