  1. main_poissons2d_hard.py is the main file using the model from model_hard.py
  2. The ansatz function used will depend on the solution. The ansatz function has to be changed in apply_hard_boundary_constraints accordingly.

Github has issues with setting up ubuntu-22.04 on github actions. So updating the yaml file to reflect runs-on 20.04
