Thank you for your reply. MeshFunction seems to manage the whole equation_systems. I wonder if there is any simpler operation that can transfer only the solutions between two different meshes? (with different partition, if possible). And a cube domain is enough for me.
I wrote a routine that transfers the solutions between two nested meshes that one is uniformly refined from another (the refined mesh has the same partition as the coarse mesh). For some reason, I want the refined mesh to be denser than the coarse one only along a particular direction, if libMesh provides another refining operation similar to 'uniformly_refine()', then my code doesn't need to be changed.
