[web] Heatconduction (Line Source Term) benchmark conversion to jupyter notebook
The benchmark 'Heatconduction (Line Source Term)' is converted to a jupyter notebook.
There are a few questions/issues remaining:
- for the reference temperature for error calculations, is it correct that the analytical solution is replaced by the numerical one due to the singularity in the region x,y < 0.01 ?
- the temperatures as shown in the first plot are different from the temperature shown in the current/existing benchmark (already discussed that with @TomFischer )
- contrary to the existing benchmark, the errors are bigger for the grid with finer resolution
