MPh is available on PyPI and can be readily installed via pip:

pip install mph

Add --user to the above command to make it a per-user installation, instead of system-wide, which may or may not be preferable. Run

pip uninstall mph

in order to remove the library from your system.

Requires JPype for the bridge from Python to Comsol’s Java API and NumPy for returning (fast) numerical arrays. pip makes sure the two Python dependencies are installed and adds them if missing.

Comsol, obviously, you need to license and install yourself. Versions from Comsol 5.3 onward are expected to work. If you want to use the client–server mode, make sure to once run comsolmphserver from a console first to enter the obligatory user name and password.
