[petsc-users] DOF projection after dmforest adaption

[Preda Silvia]

Hi,

We are having a hard time understanding how the degrees of freedom are projected after a dmforest adaption. Having used before the P4EST library directly, we recall that there, a index mapping from quadrants present in the grid before and after adaption (1 to 1, 1 to many, many to 1, for unaltered, refined, coarsened quadrants, respectively) was available. Would it be possible to access the same information for a dmforest?

Thank you for all the suggestion!

Silvia
