DUNE 1.2.1 - Release Notes

Warning: Many things have been marked deprecated. However note that class deprecation is buggy in all versions of gcc prior to 4.3.

dune-common

• Corrected version dependencies such that pkg-config can parse them.
• Fixed compatibility issue of PoolAllocator and gcc-4.3 (FS #543).
• Added copy constructor for FieldVector (to avoid warnings on an unused variable for size 0).

dune-grid

• Fixed method conforming on ALUGrid intersection iterator.
• Corrected adaptation interfaces for ALUGrid, OneDGrid and UGGrid. A test for these features was also added.
• The method name of ALUConformGrid now returns "ALUConformGrid".
• Fixed a compatiblity issue between AlbertaGrid and MPICH.
• Ported several fixes and enhancements to the generic geometries for a smoother transition.
• Fixed callback adaptation for periodic AlbertaGrid and improved the documentation.
• Fixed a failing assertion in ALU3dGrid when calling ilevelbegin.

dune-istl

• AMG: Set overlap to zero for coarse levels to avoid degradation of convergence when running parallel.
• Some solvers incorrectly stated that they converged.
• Added random access iterators to ISTL base arrays.
• AMG: Fixed an incorrect type in IndicesCoarsener.
• Make sure that some FieldMatrices are initialized.
• Fixed communication for containers with a variable size of data items per index
• AMG: Interpret positive off-diagonal values as weak couplings as the error might oscillate (fixes convergence for anistropic problems with trilinear finite elements).
• ILU preconditioners: Allow const matrices as template parameters. (Caused a compile time error before)
