3.1.3.3. fixY Command

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

Argument	Type	Description
$yCoordinate	float	y-coordinate of nodes to be constrained
$constrValues	list integer	|ndf constraint values (0 or 1) corresponding to the ndf degrees-of-freedom. 0 unconstrained (or free) 1 constrained (or fixed)
$tol	float	user-defined tolerance (optional: default = 1e-10)

Example:

The following example demonstrate the command to fix the first 3 degrees-of-freedom at all nodes in the model at y location 20.0.

1. Tcl Code

fixY 20.0 1 1 1 0 0 0

2. Python Code

fixY(20.0, 1, 1, 1, 0, 0, 0)
