[Libmesh-users] Question about the nodal solution value outputted via write_equation_systems() from L2_LAGRANGE elements

[Yuxiang W. <yw...@vi...>]

Dear all,

I am using the L2_LAGRANGE elements for stress recovery, because the stress
are not continuous over the domain. I noticed that my
stress_system.solution->size() indicate that I have more than one value for
each node and each stress component. This makes sense - I should have as
many values as the number of elements connecting to that node.

However, when I used write_equation_system() functionality and visualize in
ParaView, only one value is shown per node. I suspect that it is an average
of all element DOFs on this node but am not sure - could you please help
share a hint?

Best,
Shawn
