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.<br>
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.<br>
Should you be further interested, you are very welcome to contact
me, also by phone, if you prefer.<br>
<br>
Greetings, Benedikt<br>
<br>
PS: our curvilinear-grid manager also offers 2nd and 3rd order,
curved boundary, tetrahedra<br>

<p><span class="mx_EventTile_body" dir="auto">Dear
Alu-Grid-Community,</span></p>
<p><span class="mx_EventTile_body" dir="auto">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 <br>
