When displacements are transferred to a structural analysis, an Imported Displacement object can be inserted to represent the transfer. For applicable transfers or for specific steps to transfer data, see the Imported Boundary Conditions section.
Note:
If one or more nodes with imported displacements have nodal rotations specified on them, Mechanical attempts to negotiate and apply the imported displacements. The imported displacements are transformed to the nodal coordinate system and then applied on the node(s). However, there may be cases when a suitable transformation cannot be obtained (for example, [x,y,z] > [fixed, free, free] in the Global Coordinate System becomes [fixed, fixed, free] in the nodal coordinate system if the coordinate system is rotated about the z-axis). For such situations, Mechanical will report a conflict.
If an Imported Displacement and other support constraints are applied on common geometry or node selections, you can choose to override the specified constraints by using the Override Constraints property in the details of the Imported Displacement object. By default, the specified constraints are respected and Imported Displacement is applied only to the free degrees of freedom of a node.
If you have multiple Imported Displacements scoped to common geometry or node selections, the application could ignore some constraints and apply the Imported Displacements to only the free degrees of freedom of a node. Use the Override Constraints property to override the specified constraints.
If you have a Nonlinear Adaptive Region object present in a Static Structural analysis, the Imported Displacement includes the property: Apply To Initial Mesh. You use this property to specify whether the boundary conditions are applied directly to the initial mesh or to the newly generated mesh.
This imported loading condition supports the Vector Display options.
