# Fix command
This command is used to construct single-point homogeneous boundary constraints.
```tcl fix $nodeTag (ndf $constrValues) ```
|
integer tag identifying the node to be constrained |
|
ndf constraint values (0 or 1) corresponding to the ndf degrees-of-freedom. |
0 unconstrained (or free) |
|
1 constrained (or fixed) |
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.
