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

  1. Python Code

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