so assume you want to solve:
int_0^1 grad(u)grad(v) dx = int_0^1 v dx
on [0,1] mesh with let’s say N=5 cells (i.e. 6 nodes). For the basis, we want to use tent functions. I.e. something like this Tent functions
The cells are of width h=1/N, so they are equidistant.
I somehow fail to find out how I can use such a simple 1D mesh.
