In my code， I have to use the space with dirichelet bounary
V = NumberSpace(mesh, dirichlet=[1,2,3,4)
,It's still usable in my code, But I think it's strange. because the trial function is only 0, namely V=0 .
using a NumberSpace together with Dirichlet boundaries does not make sense to me. The NumberSpace gives a singe scalar unknown (1 dof). If this scalar is then constrained to be zero at the boundary, it will simply be zero and there are no free dofs left over.
