We use a discontinuous basis, L2_LAGRANGE, so you can do an element-local projection with no problem. The dofs are duplicated. David On Thu, Oct 12, 2017 at 12:35 PM, Renato Poli wrote: > Hi, > > I believe this is a simple conceptual doubt on FEM and stress recovery - > perhaps you can help me

[Libmesh-users] L2 Projection in example sys_of_eqn_ex6

2017-10-12 Thread Renato Poli
Hi, I believe this is a simple conceptual doubt on FEM and stress recovery - perhaps you can help me with some reference literature or brief clue... Concerning example system_of_equations_ex6. In funcion "compute_stress", it calculates a L2 projection of the stresses, element by element, right?
