This command is used to construct multiple homogeneous single-point boundary constraints for all nodes whose z-coordinate lies within a specified distance from a specified coordinate.

fixZ $zCoordinate (ndf $ConstrValues) <-tol $tol>

$zCordinate z-coordinate of nodes 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)
$tol user-defined tolerance (optional, default = 1e-10)


fixZ 0.0 1 1 1 1 1 1; # fully restrain all nodes in x-y plane at origin (z=0.0)
