Description

Two features I often miss in restarting is

  • Restarting from different (lower) polynomial degrees. Use case would be a cheaper simulation to get somewhat physical fields and then enhance quality. Another use case would be an easier comparison of solutions with different polynomial degrees.
  • Restarting a hyperbolic-parabolic simulation from a (purely) hyperbolic simulation, i.e., computing the gradients from the solution. Certainly, in that case the solution does not correspond to the equations at hand, but might still be helpful. EDIT: Already possible, see PR #2452
