Automatic processing of dymola simulation results with Python

Question

I want to automatically evaluate my simulation results with a python script, but struggle to open the .mat-Files in a meaningful way.

Opening the files with scipy.loadmat doesn't seem to be a viable option:

from scipy.io import loadmat
x = loadmat(path)

Result:

Should I implicitly return the values I want to analyse with my python simulation script or is there another way of loading .mat-Results with Python?

What do you use for such tasks? Matlab is not an option sadly.

@matth this is pretty much the answer to my question! Can you post this as the answer? Thank you so much! — Phil, Dec 06 '19 at 15:33
So, is the mat file from Dymola/Openmodelica not a "standard"-conform .mat file? — Christoph, Dec 06 '19 at 15:35
Another way could be, since you'll be using Python anyway, to use [OMPython](https://github.com/OpenModelica/OMPython). — Christoph, Dec 06 '19 at 15:36

Phil, if you [self-answer](https://stackoverflow.com/help/self-answer) your question, by giving a small example script, I would definetly upvote it! — matth, Dec 06 '19 at 19:54

By suggestion from @matth DyMat can be used to write code to automatic process dymola results:

import DyMat

d = DyMat.DyMatFile(path) 
varX = d.data("dymola.path.to.variable")

To get all the paths to all variables one can use d.names() or d.nameTree()
