Release 2.10

Changelog

• Gmsh reader learned to read and export gmsh physical entity names.

• Removed the deprecated method geomTypes() from all the grid (indexset) implementations since they have not been used nor supported by the grid interface for ages. Use types() instead. Note that types() returns an object of type IndexSet::Types, which might not be std::vector<GeometryType>. Also, the object is returned by value instead of by reference.

• Provide communicate() method in OneDGrid and IdentityGrid

• Change the IndexSet::Types type of OndDGrid and YaspGrid to std::array<GeometryType,1>.

• Grid concepts are here! A Grid can now be inspected and also its components checked for valid interfaces at compilation time using c++20 concepts. Note that, this feature is still in development and might be subject to changes.

• A new parameter ‘bisectioncompatibility’ for DGF block GridParameter was added.

• MultipleCodimMultipleGeomTypeMapper is assignable.

Python

• Improve pickling support (GridViews and some GridFunction objects can now be pickled).

• Add a prototype reader for Paraview directly based on the Python bindings. This is added to the tutorial and only demonstrates how a reader could be implemented. GridViews and GridFunctions can be pickled and then read into Paraview without going through vtu. As an example manipulation the subsampling level can be adjusted directly in Paraview so that higher order functions can be visualized.

Deprecations and removals

• Deprecated CommDataHandleIF::fixedsize() has been removed. Use fixedSize() with capital S instead.

• Remove deprecated CollectiveCommunication, use Communication instead.

• Deprecated update() member function of mappers have been removed. Use the member function update(gridView) with a grid view argument when updating the mapper after the grid or grid view changes. The interface change reflects that grid view has value semantics.

• The deprecated convenience classes LeafSingleCodimSingleGeomTypeMapper, LevelSingleCodimSingleGeomTypeMapper, LeafMultipleCodimMultipleGeomTypeMapper, LevelMultipleCodimMultipleGeomTypeMapper have been removed since they don’t comply with the new mapper interface. Just use SingleCodimSingleGeomTypeMapper and MultipleCodimMultipleGeomTypeMapper.

• Remove Yasp’s deprecated YLoadBalance interface. Use Yasp::Partitioning instead.

• Remove deprecated GmshReader’s default constructor. Either use other constructors or use static methods without constructing an object.

• Remove deprecated CMake module UseUG.cmake.
