Interpolation output #40

Closed fdrmrc closed 1 year ago

fdrmrc commented 1 year ago

The current version on master assumes we only have master cells and slaves, i.e. a fully polytopic grid. Hence it fails to represent the global solution if there are "standard deal.II cells" in the space. Fixes #36

fdrmrc commented 1 year ago

Added a test which computes L2 error for the manufactured solution $\sin(2 \pi x) \sin(2 \pi y)$. Here's the interpolated solution on the standard deal.II grid. Most of the cells are standard deal.II cells, plus some agglomerates here and there
