Specific improvements

    +
  1. Changed: GridOut::write_xfig has been improved in a number +of ways. In particular, one can now color cells based on a number +of different criteria that can be set in GridOutFlags::XFig. +

  2. New: The PETScWrappers::SparseDirectMUMPS class now allows to exploit symmetry of the matrix, using the PETScWrappers::SparseDirectMUMPS::set_symmetric_mode() function. diff --git a/deal.II/include/deal.II/grid/grid_out.h b/deal.II/include/deal.II/grid/grid_out.h index c79fae7bb0..ab84f71628 100644 --- a/deal.II/include/deal.II/grid/grid_out.h +++ b/deal.II/include/deal.II/grid/grid_out.h @@ -621,7 +621,22 @@ namespace GridOutFlags * Draw boundary lines.
