Hello Mihai,
I think SolutionTransfer is what you are looking for.

Hello,
I have a question concerning local higher-order interpolation (more
precisely, patch-wise bi-quadratic interpolation).
I start from a solution on a "fine" mesh Omega_h, with a bilinear
discrete solution u_h defined on it. I coarsen all cells in that mesh
once to get Omega_2h. I then have to build from the data on Omega_h a
bi-quadratic discrete solution u_2h. Is there API support for getting
u_2h in deal.ii?
I guess I can take every active cell on Omega_2h and get the support
point values from Omega_h that lie in that (bigger) cell, and then
build the bi-quadratic solution by hand. Due to Omega_2h being
obtained directly from Omega_h by pure coarsening, I should have
enough point values for a bi-quadratic interpolation. Is there a
cleaner way to accomplish this?
-- Thanks!
