periodic boundary condition support

[fipymigrate]

None of the examples have a periodic boundary conditions. Need to create an example with periodic BCS

Logged In: YES user_id=1116094 Periodic BCs for 1D diffusion have been added Need to add, 1) convection of a square wave 2) dendrite example could use periodic 3) Cahn-Hilliard 2D example could use periodic and need a test case for 2D Cahn-Hilliard anyway.

Logged In: YES user_id=1116094 Periodic BCs may need to be rethought in terms of a mesh. One would instantiate a PeriodicGrid1D for example rather than have peridoc BCs.

Logged In: YES user_id=1116094 Alternate idea. Instead of having a PeriodicMesh, one could simply have a method of mesh such as joinFaces(faces1, faces2) that join exterior faces so that they have cells on both sides. Also one could call unjoinFaces(faces1, faces2). If one wanted to unjoin faces. A PeriodicBoundaryCondition could still exist but it could simple call joinFaces(faces1, faces2), and make the rest of the simulation periodic.

Logged In: YES user_id=1116094 Now have two example test cases
