One-sided constraints are used to simulate the effect of an uneven distribution of melt flow around a core pin or part insert that has been constrained in one direction, but is free to move in the opposite direction. This is accomplished by setting translational degrees of freedom, at selected nodes, in all three plane directions.
The translational degrees of freedom can be set as fixed, free, or specified at a certain distance (mm). The constraints on the nodes on the opposite side of the core or part insert also need to be defined.
One-sided constraints are supported for all mesh types. They can be applied to components with the Property type Part Insert (3D) or Core (3D) and are used when performing core shift analyses.
