Hi Denis,
Thank you for the pointer! This is very helpful.
The below is my understanding (and please let me know if I am wrong):
1. If we do the L2 projection over a domain of elements, then it smooths
the stress jumps in the sense of integration. The stress would be
continuous over the domain
Thanks Denis :) I will try it.

Thanks for the replies.
The problem I am facing has two parts:
1- In deal ii, how to calculate stress at nodes based on stress at Gauss
points? Stress at nodal points is not continues. Is there any averaging
function to calculate stress at nodal points?
2- Export nodal stress tensor using DataPo
Hi Lisa,
To project from quadrature points to (continuous) FE space you can use this
function in current master branch of GitHub:

you would need to do for each component of stress and st
