exodus_elem_type()

std::string libMesh::ExodusII_IO_Helper::Conversion::exodus_elem_type

(

)

const

Returns

The string corresponding to the Exodus type for this element.

Definition at line 5542 of file exodusII_io_helper.C.

{
  return exodus_type;
}

get_inverse_node_map()

int libMesh::ExodusII_IO_Helper::Conversion::get_inverse_node_map

(

int

i

)

const

Returns

The ith component of the inverse node map for this element.

The inverse node map maps the libmesh node numbering to Exodus' node numbering.

Note

All elements except Hex27 currently have the same node numbering as libmesh elements.

Definition at line 5471 of file exodusII_io_helper.C.

{
  if (!inverse_node_map)
    return i;

const

Returns

The ith component of the inverse shellface map for this element.

Definition at line 5524 of file exodusII_io_helper.C.

{
  if (!inverse_shellface_map)
    return i + 1;

The side map maps the libMesh side numbering format to this exodus's format.

Definition at line 5497 of file exodusII_io_helper.C.

{
  // For identity side mappings, we our convention is to return a 1-based index.
  if (!inverse_side_map)
    return i + 1;
 
  libmesh_assert_less (i, inverse_side_map->size());
  return (*inverse_side_map)[i];
}

get_node_map()

int libMesh::ExodusII_IO_Helper::Conversion::get_node_map

(

int

i

)

const

Returns

The ith component of the node map for this element.

The node map maps the exodusII node numbering format to this library's format.

Definition at line 5460 of file exodusII_io_helper.C.

{
  if (!node_map)
    return i;
 
  libmesh_assert_less (i, node_map->size());
  return (*node_map)[i];
}

get_shellface_index_offset()

std::size_t libMesh::ExodusII_IO_Helper::Conversion::get_shellface_index_offset

(

)

const

Returns

The shellface index offset.

Definition at line 5552 of file exodusII_io_helper.C.

{
  return shellface_index_offset;
}

get_shellface_map()

int libMesh::ExodusII_IO_Helper::Conversion::get_shellface_map

(

int

i

)

const

Returns

The ith component of the shellface map for this element.

Note

Nothing is currently using this.

Definition at line 5513 of file exodusII_io_helper.C.

{
  if (!shellface_map)
    return i;
 
  libmesh_assert_less (i, shellface_map->size());
  return (*shellface_map)[i];
}

get_side_map()

int libMesh::ExodusII_IO_Helper::Conversion::get_side_map

(

int

i

)

const

Returns

The ith component of the side map for this element.

The side map maps the exodusII side numbering format to this library's format.

Definition at line 5482 of file exodusII_io_helper.C.

{
  if (!side_map)
    return i;
 
  // If we asked for a side that doesn't exist, return an invalid_id
  // and allow higher-level code to handle it.
  if (static_cast<size_t>(i) >= side_map->size())

Member Data Documentation

dim

int libMesh::ExodusII_IO_Helper::Conversion::dim

The element dimension; useful since we don't seem to have a cheap way to look this up from ElemType.

Definition at line 1306 of file exodusII_io_helper.h.

Referenced by libMesh::ExodusII_IO_Helper::read_elem_in_block().

exodus_type

std::string libMesh::ExodusII_IO_Helper::Conversion::exodus_type

The string corresponding to the Exodus type for this element.

Definition at line 1316 of file exodusII_io_helper.h.

invalid_id

const int libMesh::ExodusII_IO_Helper::Conversion::invalid_id = std::numeric_limits<int>::max()

static

An invalid_id that can be returned to signal failure in case something goes wrong.

inverse_node_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::inverse_node_map

Pointer to the inverse node map for this element.

For all elements except for the Hex27, this is the same as the node map.

Definition at line 1265 of file exodusII_io_helper.h.

inverse_shellface_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::inverse_shellface_map

Pointer to the inverse shellface map for this element.

Definition at line 1287 of file exodusII_io_helper.h.

inverse_side_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::inverse_side_map

Pointer to the inverse side map for this element.

Definition at line 1275 of file exodusII_io_helper.h.

libmesh_type

ElemType libMesh::ExodusII_IO_Helper::Conversion::libmesh_type

The canonical (i.e.

standard for this library) element type.

Definition at line 1300 of file exodusII_io_helper.h.

n_nodes

int libMesh::ExodusII_IO_Helper::Conversion::n_nodes

The number of nodes per element; useful likewise.

Definition at line 1311 of file exodusII_io_helper.h.

node_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::node_map

Pointer to the node map for this element.

Definition at line 1258 of file exodusII_io_helper.h.

shellface_index_offset

size_t libMesh::ExodusII_IO_Helper::Conversion::shellface_index_offset

The shellface index offset defines the offset due to a difference between libMesh and Exodus in indexing sidesets.

This is relevant for shell elements, for example, since Exodus includes extra "shell face" sides in that case.

Definition at line 1294 of file exodusII_io_helper.h.

shellface_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::shellface_map

Pointer to the shellface map for this element.

Only the inverse is actually used currently, this one is provided for completeness and libmesh_ingore()d to avoid warnings.

Definition at line 1282 of file exodusII_io_helper.h.

side_map

const std::vector<int>* libMesh::ExodusII_IO_Helper::Conversion::side_map

Pointer to the side map for this element.
