class ProcessLib::LIE::HydroMechanics::LocalDataInitializer< LocalAssemblerInterface, LocalAssemblerDataMatrix, LocalAssemblerDataMatrixNearFracture, LocalAssemblerDataFracture, DisplacementDim, ConstructorArgs >

The LocalDataInitializer is a functor creating a local assembler data with corresponding to the mesh element type shape functions and calling initialization of the new local assembler data. For example for MeshLib::Quad a local assembler data with template argument NumLib::ShapeQuad4 is created.

Attention: This is modified version of the ProcessLib::LocalDataInitializer class which does not include line elements, allows only shapefunction of order 2, and provides additional template argument DisplacementDim.

inlinestaticprivate

Generates a function that creates a new LocalAssembler of type LAData<ShapeFunctionDisplacement>. Only functions with shape function's dimension less or equal to the global dimension are instantiated, e.g. following combinations of shape functions and global dimensions: (Line2, 1), (Line2, 2), (Line2, 3), (Hex20, 3) but not (Hex20, 2) or (Hex20, 1).
