More information about the extpkgs used in the EASIFEM are given here.

In what follows details of installing these pkgs on different system is given.


The easiest way to install the above-mentioned extpkgs is through easifem command line application.

  • First, install the application:
python3 -m pip install --upgrade easifem

Then install extpkgs by using following command.

easifem install extpkgs
