If I add that ExplicitSystem as you mention, I will obtain one degree of freedom per element, and they will be actually numbered from 0 to the number of elements and will change accordingly with the refinement or coarsening, won't they? This would be pretty convenient for me because I want to perform a matrix-vector operation. The vector would be the zeroth order monomial variable and the matrix would have a size of number of elements x number of elements.
