Hi, in freemfem, is it possible to compare the finite element
solutions on uniformly refined meshes with the solution on
a very very refined one (as a reference solution), in a respectively
norm?
Thanks

Yes , you can use the solution computer on a find grid as ling an analytical solution.
a small old example:

Thanks for pointing out this.
