Detailed Description

template<unsigned int Dim, FEFamily T_radial, InfMapType T_map>
class libMesh::InfFE< Dim, T_radial, T_map >::Base

This nested class contains most of the static methods related to the base part of an infinite element. Only static members are provided, and these should only be accessible from within InfFE.

[static]

Build the base element of an infinite element. Be careful, this method allocates memory! So be sure to delete the new element afterwards.

Returns:

the base element associated to type. This is, for example, TRI3 for INFPRISM6.
