    [io][gmsh][uggrid] fix reading a Gmsh file into a parallel UGGrid · 8728f7f9
    Bernd Flemisch authored
    Depending on the Dune version, the boundary markers are present on
    all processes (<= 2.6) or on the root process only (>= 2.7). Try to
    handle this in a flexible way in the corresponding data handle:
    Determine if the minimum size over all processes of the boundary
    markers vector is zero. If yes, assume that the root process contains
    all markers and broadcast them.
    
    Currently, it isn't possible to refine a parallel UGGrid that has
    been read by a GmshReader, see dune-grid issue #83. Therefore, don't
    refine in the corresponding test.
