Structure Constraints on Geometry
When you define structure constraints for geometry, keep the following points in mind:
Any point, curve, or surface you constrain must be associated with at least one element. To check associations with geometry that will be meshed, click the constraint icon on the model or select the constraint in the Model Tree. Creo Simulate highlights the constraint icon and associated geometry.
A structure boundary condition defined at a point or on a curve can result in theoretically infinite stresses. See Handling Stress Concentrations for information on working around this problem.
Any constrained curve constrains the edges, beams, or 2D shells that lie on that curve.
Any constrained surface constrains the shells, solid faces, 2D solids, or 2D plates that lie on that surface.
Any constrained edge constrains the beams and 2D shells that lie on that edge.
