[Libmesh-users] L2 Projection in example sys_of_eqn_ex6

[Renato P. <re...@gm...>]

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?

My doubt is related to setting the degree of freedom values in:
>> stress_system.solution->set(dof_index, projected_data(index));

Won't multiple elements set  the same dof? Will it be set multiple times?
Did I miss something?

Thanks,
Renato
