# node¶

Query.node(x, y, z)

Return node closest to coordinate `(x, y, z)`.

Number of the selected node nearest the x, y, z point. (In the active coordinate system, lowest number for coincident nodes.) A number higher than the highest node number indicates that the node is internal (generated by program).

Parameters
x`float`

X-coordinate in the active coordinate system

y`float`

Y-coordinate in the active coordinate system

z`float`

Z-coordinate in the active coordinate system

Returns
`int`

Node number

Examples

In this example we construct a solid cube and mesh it. Then we use `queries.node` to find the node closest to the centre of the cube. Using this we can extract the coordinates of this node and see how close to the centre the node is.

```>>> from ansys.mapdl.core import launch_mapdl
>>> mapdl = launch_mapdl()
>>> mapdl.prep7()
>>> mapdl.et(1, 'SOLID5')
>>> mapdl.block(0, 10, 0, 10, 0, 10)
>>> mapdl.esize(3)
>>> mapdl.vmesh('ALL')
>>> node_number = mapdl.queries.node(5., 5., 5.)
>>> node_number
112
>>> x = mapdl.queries.nx(node_number)
>>> y = mapdl.queries.ny(node_number)
>>> z = mapdl.queries.nz(node_number)
>>> (x, y, z)
(5.0, 5.0, 5.0)
```
Return type

`int`
