Hello, I’m working on a parallel-in-time method and for the spatial discretization I’m using dolfinx. The method that I use is multilevel and employ a hierarchy of meshes in a multigrid fashion (PFASST). It is known that for efficiency the prolongation interpolator should be high order. So I was w…

High order interpolation between two meshes

In general, the prolongation/restriction operator can be implicitly enforced using the non-matching interpolation.
