a Python-based, open-source, multidisciplinary optimization framework with support for analytic derivatives and distributed HPC computing

OpenMDAO is a Python-based open-source multidisciplinary design, analysis, and optimization (MDAO) framework which specializes in large-scale problems requiring parallel execution, distributed memory, and complex problem formulations.

OpenMDAO has been used to solve a number of interesting design problems, including optimization of a cubesat platform (CADRE) (paper), wind turbine and wind farm design (paper), aircraft trajectory optimization, and turbomachinery design for jet engines (paper).

The OpenMDAO project is managed by a development team at the NASA John H. Glenn Research Center in Cleveland OH.

For documentation, see http://openmdao.org/docs.

Our code base is hosted at Github: http://github.com/OpenMDAO/OpenMDAO-Framework

Does openmdao optimization drivers support array types, if only one objective is present?

I have setup an objective function - obj = (x0-u0)^2 + (u0)^2 I am calculating the minima using Scipyoptimizer with SLSQP. I give x0 as input and hence it computes u0 on the fly, simultaneously minimizing the obj also. Now, I am trying to use array…

How to check for missing partials

I implemented a system that is composed of few groups and multiple components. It is relatively intricate and has component inputs/outputs, which some partials are dependent/non dependent etc. Gradient based optimizers seem to get stuck at the…

Why does SLSQP take such an unusual optimisation route?

The gist for the script is available here: https://gist.github.com/eufren/3f53eb285c7f426e678e1d63926fb34a The total derivatives seem to be basically correct when I use p.check_totals() - typical relative difference is about 1e-5, with a maximum of…
