<br>
I moved this question from the dune mailing list to the
dune-pdelab mailing list.<br>
<br>
Here is the problem:<br>
I
computed stresses at the Gauss points resulting from the
deformation
gradients in my local operator. Now I wonder, how I can
visualize these
stresses via vtkwriter directly from the local operator,
which is on
element basis, without a second calculation of the variable
in the
driver *_Q2.hh or somewhere else? Or is there a way to
assign these
stress values to a vector container and visualize it in the
driver
*_Q2.hh?<br>
<br>
Maybe it is possible to extrapolate these values to the
nodes within the operator and assign the values to a vector
container,
which in turn can be visualized by the vtkwriter?<br>
<br>
Is this there a solution for this problem?<br>

Dear Christian,<br>
<br>
Just to clarify: <br>
<br>
Do you have the deformation as primary variable for which you solve
and with this solution you reconstruct the stress?<br>
<br>
If that is true I don't get why do you have the stress in the local
operator.<br>
<br>
Or do you use a mixed approach, where you solve for the stress and
deformation? But then you still would get the solution not in the
operator but in the driver as a solution vector.<br>
<br>
