Hi there, I have a question about the usage of a `DiffusionIntegrator` as a Boundary Integrator, and the behavior I should expect when doing so. To understand why I even...

ND_R2D visualization with glvis fails

glvis seems not capable of visualizing the ND_R2D elements. To reproduce, run example 31: ``` ex31 -m ../data/star.mesh -o 2 ``` and try to visualize with glvis, with the command...

Gradient of an L2 / DG solution
