### 2.3.9. Explicit Node Pairing

The following routine provides a method for explicitly marking two nodes as being identical (or in the same position in space).

#### 2.3.9.1. cfxImportMap

    ID_t cfxImportMap (nodeid, mapid)
    ID_t nodeid, mapid;

Explicitly map the node identified by `nodeid` to the node identified by `mapid`.

On calling `cfxImportDone` the Mesh Import API will update regions and elements referencing the mapped node to the node it is mapped to. This therefore reduces the total node count imported to CFX and eliminates the duplicate nodes.

Duplicate nodes may also be removed by CFX if the appropriate options are selected in the CFX interface and an appropriate tolerance set. For details, see Importing Meshes in the CFX-Pre User's Guide.
