FixMacroZ_max

FixMacroZ_max(dofs: List[int], tol: float = 1e-10)

Bases: SPConstraint

Boundary constraint at the maximum Z-coordinate macro boundary.

FixMacroZ_max constrains selected degrees of freedom for all nodes sharing the maximum Z coordinate of the model. The boundary coordinate is defined using the global TCL variable $Z_MAX.

Tcl form

fixZ $Z_MAX <dof1> <dof2> ... -tol <tol>

Example

from femora.core.model import Model

model = Model()
# Fix Z DOF of all nodes at the maximum Z macro boundary
constraint = model.constraint.sp.fix_macro_z_max(
    dofs=[0, 0, 1],
    tol=1e-5,
)

Create a maximum Z macro boundary constraint.

Parameters:

Name	Type	Description	Default
`dofs`	`List[int]`	List of DOF constraint states. 0 indicates unconstrained (free). 1 indicates constrained (fixed).	required
`tol`	`float`	Tolerance for coordinate comparison.	`1e-10`
