Fixed Constraint
Use the Fixed Constraint node to set all displacements on the selected geometric entity (boundary, edge, or point) to zero.
To constrain interfaces between the material layers, use Fixed Constraint, Interface.
Shell Properties
Select the layer or layers on which this constraint is to be used.
Table 6-35: Layer Selections; Fixed Constraint.
Selection
Use All Layers
Selection of Individual Layers
Boundary, Edge, Point
Same as interface selection when the node is added.
When Use all layers is not selected.
Only a subset of the layers selected in the physics interface can be selected.
•
All other settings for the Fixed Constraint node are described in the documentation for Fixed Constraint in the Solid Mechanics interface.
•
For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.
