build_elem()

std::unique_ptr< const Elem > libMesh::InfFEBase::build_elem ( const Elem *  inf_elem )

static

Build the base element of an infinite element.

Here "base" refers to the non-infinite/traditional geometric element face which is associated with this infinite element. A const base Elem is built from a const input InfElem.

{
  return inf_elem->build_side_ptr(0);

get_elem_type()

ElemType libMesh::InfFEBase::get_elem_type ( const ElemType  type )

static

Returns

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

n_base_mapping_sf()

unsigned int libMesh::InfFEBase::n_base_mapping_sf ( const Elem &  base_elem, const Order  base_mapping_order  )
