periodic conforming grid
From an email bei Lea:
Dear Alu-Grid-Community,
is there a way to use periodic boundary conditions and adaptive refinement with a triangular (conforming) 2D-2D (or 2D-3D)-AluGrid? As long as I use no adaptive refinements everything works as expected. I use a square with one periodic boundary generated with a dgf-file and a "walking circle" for testing. As soon as I try to use adaptive refinement and the circle approaches the domain boundary (the periodic boundary region is refined), the program runs in an infinite loop, just printing the warning
(**WARNING (IGNORED) in Periodic3Top < A >::refineBalance (..) , file dune-alugrid/dune/alugrid/impl/parallel/../serial/gitter_tetra_top.cc line 2708 periodic refinement is only implemented for isometric refinement!)
If this is not implemented, are there any plans to add this in a future release?
Second question: Is there any way to generate a periodic AluGrid directly, without a dgf-file?
Thanks for all help and suggestions!
Best, Lea
