3.1.3.4. fixZ Command

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.

Argument

Type

Description

$zCoordinate

float

z-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 z location 30.0.
