Dear Christian,<br>
<br>
if I understood correctly you have a solution vector with the
stresses and you now want to interpolate the solution to the Gauss
points.<br>
<br>
As far as I know there is no direct possibility but you can use the
DiscreteGridFunction and the GridFunctionToFunctionAdapter to
compute your solution at any geometrical point.<br>
<br>
If I understood it correctly this is only necessary if, e.g. you
have a nodal value solution and Q2 and your visualization tool only
supports linear interpolation otherwise you can just tell your
visualization tool which basis function to use.<br>
<br>
If there is an easier way I am very interested in it, too!<br>
<br>
Best,<br>
Nicolas<br>

we successfully implemented a continuum mechanical model into
dune-pdelab - thanks to Markus Blatt :o)<br>
<br>
Therein in, we compute the stress resulting from deformations.
We would like to visualise the values computed at the Gauss
points within the operator. It would be great, if this would be
more or less directly possible. For one variable it may be ok to
implement the computation of the variable once again somewhere
else. For a more complicated situation, this may get somehow
problematic, since it is not really convenient and fail-save to
implement all the computed and required variables within the
operator a second time some where else. <br>
<br>
Is there a solution for our problem? Any help would be greatly
appreciated.<br>
<br>
Best wishes for the evening,<br>
