compute_totals returns the wrong total derivatives when approx_totals is not used

QUESTION

compute_totals returns the wrong total derivatives when approx_totals is not used

Asked 2020-Feb-18 at 17:34

I noticed that prob.compute_totals() returns a wrong answer when prob.model.approx_totals() is not specified before. Having the partial derivative manually defined or computed by finite differences doesn't change anything, the answer remains wrong when not calling prob.model.approx_totals() before. Also, the call to compute_totals is actually faster when approx_totals is called before, compared to when it's not. This seems counter-intuitive with manually defined partials, since approx_totals is supposed to add an unnecessary finite-difference computation.

Here is a MWE with the Sellar example taken from the OpenMDAO documentation. I also noticed the same behaviour in OpenAeroStruct, even though the differences are smaller than in this example.

In this example, the problem is that you have a cycle in SellarMDA, but the model does not contain a linear solver that can compute the total derivatives across the cycle. One way you can check on this is to run "openmdao check myfilename.py" at the command-line. I ran it on your model, and got the following warnings:

Install OpenAeroStruct

You can install using 'pip install OpenAeroStruct' or download it from GitHub, PyPI.
You can use OpenAeroStruct like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
