Hi together, also just to add this in case someone it interested. There also has been some more work lately on using Dumux from Python via pybind11 bindings. Some first full application (1p test) can be found here: https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/master/test/python/test_1p.py <https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/master/test/python/test_1p.py> We haven’t announced this properly yet because it’s still in it’s infancy, and more classes need wrappers and some issues are still not solved.
