FixX command

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

fixX $xCoordinate (ndf $ConstrValues) <-tol $tol>

---

$xCoordinate	x-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)

EXAMPLE:

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