Add tie constraint
The fibers and the elastomeric tube need to be connected to each other in some way, and this connection is modeled as a ‘tie constraint’, which ties the fibers to the surface of the actuator. To apply this constraint, double click on Constraints in the model tree. Accept the default type of ‘tie’ and click Continue.
- Choose ‘Surface’ as the master type.
- Click on Surfaces in the bottom right corner, select ‘Merged_Actuator-1.OuterSurf’, and click Continue.
- Choose ‘Node region’ as the slave type. Select ‘fibers-1.FiberSet’ and click Continue.
- Click OK in the ‘Edit Constraint’ dialog box to impose the constraint.
