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

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)

EXAMPLE:

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.
