Function Documentation

int ex_get_n_coord	(	int	exoid,
		int	start_node_num,
		int	num_nodes,
		void *	x_coor,
		void *	y_coor,
		void *	z_coor
	)

reads the coordinates of the nodes. Memory must be allocated for the coordinate arrays (x_coor, y_coor, and z_coor) before this call is made. The length of each of these arrays is the number of nodes in the mesh. Because the coordinates are floating point values, the application code must declare the arrays passed to be the appropriate type "float" or "double" to match the compute word size passed in ex_create() or ex_open()

Parameters:

	exoid	exodus file id
	start_node_num	the starting index of the coordinates to be returned.
	num_nodes	the number of nodes to read coordinates for.
[out]	x_coor	Returned X coordinates of the nodes. These are returned only if x_coor is non-NULL.
[out]	y_coor	Returned Y coordinates of the nodes. These are returned only if y_coor is non-NULL.
[out]	z_coor	Returned Z coordinates of the nodes. These are returned only if z_coor is non-NULL.
