Dear all,
I am trying to insert experimental data from a file at the output boundary
of a tube.
Is it possible to do that in deal.II? I attach the file of experimental
data, pressure vs time.
Thanks for any help.

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 (anything, either example, code, or paper)?
That all depends on what equation exactly you're lookin
Thank you Professor Bangerth for your response! Yes that's exactly what I
am interested in.

Hi Wolfgang,
This time I used VectorOperation::insert and it didn't happen the memory
error that I posted before.
However, if I put the compress function after the loop, it only sets one
entry on each rank then throws the exception
"Object is in wrong state, not for unassembled matrix."

Thank you so much Bangerth!
Now I understand why we need to rewrite the error formula on a cell as
residual times dual weight. But I'm still a little confused with the reason
why we must introduce z_h.
Just as you mentioned, if we introduce z_h, then z-z_h is a quantity that
is only large wher
Jane,
I believe the formula is correct. the cubic term comes from p=z^3 being the
pressure manufactured solution. so in (pI-2e) you get a z^3 term and indeed a
linear term in the 2e portion.
I see. I missed that there is of course also a pressure.
This is how I have come to conclude that i

Shawn,
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?
That depends on how exactly you define "shell elements". But if you mean
"elemen
I had a similar issue (returning NaN) when dealing with a 3D HyperBall mesh.
I realized the problem was that the face I was trying to measure was not
planar enough.
There's a tolerance condition that has to be fulfilled at this line of the
measure function.
