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
Exactly what I was looking for! Thank you so much Professor Bangerth.
Have a great one,

Dear all,
While I can use the shape_grad function to get the gradient of the shape
function with respect to the real cell coordinates, would there be a way to
get the shape_grad with respect to the reference natural coordinates? For
example, for shell element (that I'm working on), I have the
n.

Oh and another detail - the mesh is not really 2D mesh because the four
nodes of a quad element may not be co-planar. Therefore, there does not
exist a transform that can reduce the mesh to 2D.

Hi Daniel,
Thank you for your help! I just tried a code snippet (modified step-49)
below and it does not work, either when I set the dim=2 or dim=3.
```
int main ()
{
Triangulation<2> triangulation;
GridIn<2> gridin;
gridin.attach_triangulation(triangulation);

Dear all,
Sorry for the beginner question.
I am trying to load a 3D quad mesh (i.e. not all nodes are co-planar for
one element) to implement a Mindlin–Reissner plate. I wonder, can GridIn
class read such meshes? Upon reading the document, it seems like if the
input element is quad then it is

Hello dear deal.II community,
Previously, I thought that for a high order element in 1D (cubic, for
example), the interior nodes would be equally distributed at:
Node 0 - 0
Node 1 - 0.01
Node 2 - 0.0033
Node 3 - 0.0067
However, in deal.II I found them to be at:
Node 0 - 0
Node 1 -
Thank you Professor Bangerth for the answer! I appreciate your link to the
video a lot. And thank you for the kind words - I'll try to work harder to
match your expectations and one day contribute to deal.II :)

Dear all,
Sorry for the spam - a basic mathematical question.
In the step-3 example
(https://www.dealii.org/8.4.1/doxygen/deal.II/step_3.html), I noticed that
at first the variable phi is used as a test function. It is in the same
space with u, except for that the value is 0 on the

Hi Professor Bangerth,
Thank you for the pointer! Those are very helpful. I just realized that
Mindlin-Reissner plate theory can be expressed in forms of mixed elements.
My current need for shell element is for solid mechanics problem
(Mindlin-Reissner plates). A simple example could be that a

Short summary: cmake runs examples fine when I run it in the pre-installed

help see why?
Full story: first, when I run it in the pre-installed src example folder,
it works:

Thank you Professor Bangerth for your response! Yes that's exactly what I
am interested in.
I am excited to learn that there are arguably better methods (mixed
methods) to solve shell problems. I am not familiar with those; could you
please kindly provide some pointers for me to start
Hi,
Sorry for the spam.
I tried to search but did not find an implementation of shell elements in
deal.II. Since this is a commonly used element, I'd like to make sure that
it's not me missing it. Could you please help confirm?
Best,
Shawn
