There was a problem hiding this comment.
These are the only defaults currently in OpenMDAO:
DEFAULT_OPT_SETTINGS['IPOPT'] = {
'hessian_approximation': 'limited-memory',
'nlp_scaling_method': 'user-scaling',
'linear_solver': 'mumps'
I see we change nlp_scaling_method here in Aviary, and it is probably intentional, so we should probably just set it.
