You should take care when deleting or renaming objects, such as materials and amplitudes, that may be referred to by other objects. For example, if you delete or rename a material, the sections that refer to the material become inconsistent. To resolve the missing reference, you can edit the section and refer to a new material, or you can create a new material with the same name as the deleted material.
Table 3–1 lists objects that are commonly referred to by other objects.
Table 3–1 Objects that are commonly referred to by other objects.
| This object | Can be referred to by these types of objects |
|---|---|
| Material | Section |
| Profile | Section, skin |
| Section | Section assignment |
| Interaction | Output request, contact controls |
| Interaction property | Interaction |
| Amplitude | Load, predefined field, boundary condition, interaction |
| Connector section | Connector section assignment |
| Region (set or surface) | Boundary condition, predefined field, load, interaction, constraint, connector section assignment, output request, section assignment, beam section orientation, material orientation, output request, DOF monitor, adaptive mesh domain |
| Load | Load case, output request |
| Boundary condition | Load case |
| Datum coordinate system | Boundary condition, connector section assignment, material orientation, constraint |
| Datum plane | Load |
| Datum axis | Load |
| Datum point | Constraint |
| Part instance | Constraint |
| Part | Part instance |
Parts and part instances behave slightly differently. If you delete a part after you have instanced the part in the Assembly module, Abaqus/CAE suppresses the part instance in the assembly. You can delete the instance from the assembly. Alternatively, if you then create a new part that uses the same name, you can unsuppress the part instance to include it in the assembly. In addition, if you rename a part or a datum, objects that refer to the part or datum refer to the new name; and, as a result, the reference does not become inconsistent.
