I am not sure if this is the right place to report this.
In one of the following figures, the color plot doesn't math the contour plot,
is this the problem with VISIT?
Can you explain how the way you created the two figures differ?
Visit visualizes things by splitting each quad into two along one of the two
diagonals, and then using a linear approximation on each triangle. These do
not necessarily correspond to the bilinear function that you are outputting,
and may be the difference between the pseudocolor plot and the isocontour plot
(neither of which are equal to the P2 function in deal.II).
You can probably get a better picture by providing a positive argument to the
build_patches() function.
