- Deprecated:
- Use ex_get_id_map()(exoid, EX_ELEM_MAP, elem_map)
The function ex_get_elem_num_map() reads the optional element number map from the database. See Section LocalElementIds for a description of the element number map. If an element number map is not stored in the data file, a default array (1,2,3,. .. num_elem
) is returned. Memory must be allocated for the element number map array ({num_elem} in length) before this call is made.
- Returns:
- In case of an error, ex_get_elem_num_map() returns a negative number; a warning will return a positive number. Possible causes of errors include:
- data file not properly opened with call to ex_create() or ex_open()
- if an element number map is not stored, a default map and a warning value are returned.
- Parameters:
-
[in] | exoid | exodus file ID returned from a previous call to ex_create() or ex_open(). |
[out] | elem_map | Returned element number map. |
The following code will read an element number map from an open exodus file :
int *elem_map, error, exoid;
\comment{read element number map}
elem_map = (int *) calloc(num_elem, sizeof(int));
error = ex_get_elem_num_map (exoid, elem_map);
\comment{Equivalent using non-deprecated function}
error = ex_get_id_map(exoid, EX_ELEM_MAP, elem_map);
