[Dune] Periodic ALUGrid

[Benedikt Oswald]

Dear Lea, our own grid, i.e. the curvilinear-grid, cf. dune website 
offers periodicity in parallel operation in all directions; it does 
however not yet have refinement.
In case you need refinement, you would have to generate a refined 
version directly in gmsh. The curvilinear grid reads GMSH files 
directly, in parallel.
Should you be further interested, you are very welcome to contact me, 
also by phone, if you prefer.

Greetings, Benedikt

PS: our curvilinear-grid manager also offers 2nd and 3rd order, curved 
boundary, tetrahedra
