Detailed Description

This class forms the foundation from which generic finite elements may be derived. In the current implementation, the templated derived class FE offers a wide variety of commonly used finite element concepts. Check there for details. Use the FEAbstract::build() method to create an object of any of the derived classes.

Note
In the present design, the number of virtual members is kept to a minimum for performance reasons, although this is not based on rigorous profiling.

All calls to static members of the FE classes should be requested through the FEInterface. This interface class approximates runtime polymorphism for the templated finite element classes. Even internal library classes, like DofMap, request the number of DOFs through this interface class. This approach also enables the co-existence of various element-based schemes.

protectedpure virtual

After having updated the jacobian and the transformation from local to global coordinates in FEMap::compute_map(), the first derivatives of the shape functions are transformed to global coordinates, giving dphi, dphidx, dphidy, and dphidz. This method should rarely be re-defined in derived classes, but still should be usable for children. Therefore, keep it protected. This needs to be implemented in the derived class since this function depends on whether the shape functions are vector-valued or not.

Implemented in libMesh::FEXYZ< Dim >, libMesh::InfFE< Dim, T_radial, T_map >, libMesh::FEGenericBase< OutputType >, and libMesh::FEGenericBase< FEOutputType< T >::type >.

Reinitializes all the physical element-dependent data based on the edge of the element elem. The tolerance parameter is passed to the involved call to inverse_map(). By default the element data are computed at the quadrature points specified by the quadrature rule qrule, but any set of points on the reference edge element may be specified in the optional argument pts.

This is at the core of this class. Use this for each new element in the mesh. Reinitializes the requested physical element-dependent data based on the current element elem. By default the element data are computed at the quadrature points specified by the quadrature rule qrule, but any set of points on the reference element may be specified in the optional argument pts.

Note
The FE classes decide which data to initialize based on which accessor functions such as get_phi() or get_d2phi() have been called, so all such accessors should be called before the first reinit().
