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.
fixY $yCoordinate (ndf $ConstrValues) <-tol $tol>
For example, this command is used when specifying boundary conditions for a series of nodes lying in a plane parallel to the x-z plane in global coordinates.
$yCoordinate |
y-coordinate of nodes to be constrained |
|
$ConstrValues |
constraint type (0 or 1). ndf values are specified, corresponding to the ndf degrees-of-freedom. The two constraint types are: |
|
|
0 |
unconstrained |
|
1 |
constrained |
$tol |
user-defined tolerance (optional, default = 1e-10) |
|
EXAMPLE:
fixY 0.0 1 1 1 1 1 1 -tol 0.1; # fully restrain all nodes in x-z plane at origin (y=0.0)
