Hello I want to assign the values of a variable that I am interpolating with a QUAD4 LAGRANGE element. My idea is iterate over the elements, for each element iterate over the nodes using get_node(), and obtain the node degree of freedom using Node::dof_number(system_number,var_number,comp_number). Then use that degree of freedom to assign a value in the system->solution vector. I was wondering what would happen if instead of using QUAD4 LAGRANGE, I switched to CONSTANT, MONOMIAL, where the nodes don’t have degrees of freedom, but just the elements. Will I still obtain four nodes and then obtain the same degree of freedom whenever I call Node::dof_number() ?
