Thank you for your prompt response. My use case can be described as follows 1) Create a triangulation in Python, refine some cells (several times) 2) Serialize the triangulation in to file using Triangulation::save 3) Load the triangulation from file using Triangulation::load 4) Reconstruct a parallel::distributed::Triangulation from the serial Triangulation
So my question is how to reconstruct a *parallel::distributed::Triangulation* from a *serial* Triangulation (with hanging nodes, n_levels() greater than 2)?
