The Tie object defines two surfaces to be tied together for the duration of a simulation.
The Tie object is derived from the Constraint object.
import interaction mdb.models[name].constraints[name]
This method creates a Tie object.
mdb.models[name].Tie
Required arguments
A String specifying the constraint repository key.
A Region object specifying the name of the master surface.
A Region object specifying the name of the slave surface.
Optional arguments
A Boolean specifying whether initial positions of tied slave nodes are adjusted to lie on the master surface. The default value is ON.
A SymbolicConstant specifying the method used to determine the position tolerance. Possible values are COMPUTED and SPECIFIED. The default value is COMPUTED.
A Float specifying the position tolerance. The positionTolerance argument applies only when positionToleranceMethod=SPECIFIED. The default value is 0.0.
A Boolean specifying whether rotation degrees of freedom should be tied. The default value is ON.
A SymbolicConstant specifying the method used to determine the constraint ratio. Possible values are DEFAULT and SPECIFIED. The default value is DEFAULT.
A Float specifying the fractional distance between the master reference surface and the slave node at which the translational constraint should act. The constraintRatio argument applies only when constraintRatioMethod=SPECIFIED. The default value is 0.0.
A SymbolicConstant specifying the discretization method. Possible values are SOLVER_DEFAULT, NODE_TO_SURFACE, and SURFACE_TO_SURFACE. The default value is SOLVER_DEFAULT.
A Boolean specifying whether shell element thickness is considered. The default value is ON.
Return value
A Tie object.
Exceptions
This method switches the master and slave surfaces of a tied constraint. This command is valid only during the step in which the interaction is created.
Arguments
Return value
Exceptions
This method modifies the Tie object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the Tie method, except for the name argument.
Return value
Exceptions
The Tie object has members with the same names and descriptions as the arguments to the Tie method.
In addition, the Tie object has the following member:
A Boolean specifying whether the constraint is suppressed or not. The default value is OFF.
