[Dune] Parallel Computation on Conformal ALUGrids

[Jayesh Badwaik]

Dear DUNE,

I was looking at the DUNE doxygen documentation (the link to that specific
page is given below) and I had from there that ALUGrid supports parallel if
the grid is conformal. Is my interpretation correct or is it just a property
which is yet to be implemented?


http://www.dune-project.org/doc/doxygen/dune-grid-html/struct_dune_1_1_capabilities_1_1is_leafwise_conforming_3_01_a_l_u_conform_grid_3_012_00_01dimworld_01_4_01_4.html#_details




Cheers and Regards,
Jayesh Vinay Badwaik
