# Fix command

This command is used to construct single-point homogeneous boundary constraints.

```tcl fix $nodeTag (ndf $constrValues) ```

nodeTag

integer tag identifying the node to be constrained

constrValues

ndf constraint values (0 or 1) corresponding to the ndf degrees-of-freedom.

0 unconstrained (or free)

1 constrained (or fixed)

## Examples

fix 1 1 1 1 1 1 1; # node 1: fully fixed

fix 2 0 1 0 0 1 0 # node 2: homogeneous constraints (movement = 0) at dof 2 and 5 only.
