Function Documentation

ex_get_node_num_map()

int ex_get_node_num_map	(	int	exoid,
		void_int *	node_map )

Deprecated

Use ex_get_id_map()(exoid, EX_NODE_MAP, node_map)

The function ex_get_node_num_map() reads the optional node number mapnode number map from the database. See Section LocalNodeIds for a description of the node number map. If a node number map is not stored in the data file, a default array (1,2,3,. .. num_nodes) is returned. Memory must be allocated for the node number map array (num_nodes in length) before this call is made.

Returns

In case of an error, ex_get_node_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 a node 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]	node_map	Returned node number map.

The following code will read a node number map from an open exodus file :

int *node_map, error, exoid;
 
\comment{read node number map}
node_map = (int *)calloc(num_nodes, sizeof(int));
error = ex_get_node_num_map(exoid, node_map);
 
\comment{Equivalent using non-deprecated function}
error = ex_get_id_map(exoid, EX_NODE_MAP, node_map);
