Specific improvements

    +
  1. Changed: The cells of coarse meshes in + parallel::distributed::Triangulation used to be ordered in a Cuthill-McKee + numbering, which yields very high surface-to-volume ratios of the individual + processors' partition in case the coarse mesh consists of many cells, in + particular in 3D. The algorithm now uses SparsityTools::reorder_hierarchical + in order to get more compact partitions, similarly to the z-ordering applied + by p4est. +
    + (Martin Kronbichler, 2015/04/10) +
  2. + +
  3. New: There is now a new method + GridTools::get_vertex_connectivity_of_cells. +
    + (Martin Kronbichler, 2015/04/10) +
  4. + +
  5. New: There is now a new method SparsityTools::reorder_hierarchical to + sort nodes of a graph (sparsity pattern) in a z-like way by hierarchical + grouping of neighboring nodes. +
    + (Martin Kronbichler, 2015/04/10) +
  6. + +
  7. Changed: The methods SparsityTools::reorder_Cuthill_McKee and + GridTools::get_face_connectivity_of_cells used to take a SparsityPattern as + argument. The data type has been changed to DynamicSparsityPattern in order + to avoid copying things around. The old interface is still available but + marked as deprecated. +

  8. +
  9. Fixed: Added missing hp-related functions to FE_Q_Hierarchical together with a couple of unit tests. Improved code comments.

  10. +
  11. Fixed: deal.II did not compile on 32-bit systems when using newer p4est versions (1.0 and later) due to a type mismatch. This is now fixed.

  12. +
  13. Changed: In the spirit of the changes made to the distinction between Point and Tensor objects discussed above, the first argument to GridTools::shift() has been changed from a Point to a Tensor@<1,dim@>.
    (Wolfgang Bangerth, 2015/04/02) -
  14. +
  15. New: There is now a new quadrature formula in quadrature_lib. It is now possible to use Telles' quadrature rules through the function QTelles to integrate singular integrals

  16. +
  17. New: Added FE_Bernstein: a scalar finite element based on Bernstein basis polynomials.
