Hi Gridap, I have been exploring Gridap.jl, and I would like to contribute a small tutorial demonstrating how to set up a Poisson equation with boundary conditions, focusing on mesh...

This PR expands the Poisson tutorial with additional explanations to help beginners. I added: • Intro explanation of the weak form and how it connects to a(u,v) and b(v) •...
