I'm pretty new to this project. thanks for your fabulous job. I want to implement a hp-adaptive dg solver based on libmesh. So I read that famous paper, libMesh: A C++ Library for Parallel Adaptive Mesh Refinement/Coarsening Simulations. However, it mentioned that the p-adaptation will be support in the future. I know it is kind of outdated. So does libmesh support p-adaptation now?
P.S. How about the test coverage of the code? I found out the test project is kind of old and the lasted committing is several years ago. Does libmesh have unit test or regression test? Thanks a lot.
