Older Versions

OpenMDAO 1

To see documentation from the stable and usable 1.7.3 (and any other versions of 1.x.y), visit readthedocs. (Other, older 1.x.y versions, are available in the lower-right corner drop-down menu.)

OpenMDAO 0

To see documentation from the 0.x.y days…we’ll, we’d recommend against it, because we no longer support it!  But if you’re dead-set on running the vintage stuff, you can find it deep in our archives.
