Resolve label conflicts in your assembly FEM files

Label conflicts occur when any label number or range of numbers overlaps with the labels of the same entity type in different FEM component and subassembly files in the same parent assembly FEM file. For example, if a FEM component has node labels of 1–10,000 and a different FEM component in the same assembly FEM has a node label within that same range, a label conflict occurs.

When you use the Assembly Label Manager command on the topmost assembly FEM file, you can view all of the label conflicts for all of the entity types. A component FEM has a status of Conflict  if it has an offset range for its labels that overlaps with the offset range of other component FEM files in the assembly FEM. A subassembly has a status of Internal Conflict  if a label conflict exists between the components of that subassembly.

You can use the Assembly Label Manager dialog box to automatically or manually resolve label conflicts in the component FEMs of an assembly FEM by adding offsets to the label values. These offsets apply only in the context of the assembly FEM file; no changes are made to the labels in the original, standalone FEM files.

If your assembly FEM file contains subassembly FEM files, you can:

• Use the Automatic Component Sub-Assembly Label Conflicts command to automatically resolve all of the label conflicts in all of the subassembly FEM files. You can then resolve the any label conflicts in the parent assembly's component FEM files.

• Make each subassembly FEM file the work part and then use the Assembly Label Manager dialog box to automatically or manually resolve any label conflicts in its component FEM files.

Tip:

Always resolve all of the subassembly FEM conflicts before you resolve any top-level component FEM conflicts because resolving conflicts in child subassembly files can affect the numbering in the parent subassemby and component FEM files.

Be sure to resolve all label conflicts every time you edit a component FEM.

Resolve component FEM label conflicts automatically

1. In the Simulation Navigator, right-click the assembly FEM node and choose Assembly Checks→Assembly Label Manager.

2. In the Labels group, examine the current status of component FEM labels in your assembly FEM by clicking each of the tabs to view label status for each entity type.Conflict appears in the Status column if the component FEM's label range conflicts with other components.

3. Select an offset type:Same Offsets in Component—For each component, the offset is the same for nodes, elements, coordinate systems, physical properties, groups, plies, and modeling objects. The software calculates the highest-needed offset and applies it uniformly to all offsets within the component. The nodes, elements, coordinate systems, physical properties, groups, plies, and modeling objects start with the same ID number in each component. One value is used for Offset to Nearest. Same Nearest Value for All—For each component, the offset is calculated independently for nodes, elements, coordinate systems, physical properties, groups, plies, and modeling objects. One value is used for Offset to Nearest. Separate Nearest Value for All—Lets you specify different Offset to Nearest values for nodes, elements, coordinate systems, physical properties, groups, plies, and modeling objects. For each component, the offset is calculated independently for nodes, elements, coordinate systems, physical properties, groups, plies, and modeling objects.

4. Specify a nearest offset value. Choose an order of magnitude from 1–100000.For example, if you have two components with a label range of 1–250, and you specify a nearest offset value of 100, the second component will have an offset of 300 applied. If you specify a nearest offset of 10, the second component will have an offset of 260 applied.

5. (Optional) Specify an Additional Top Offset value.This is useful to ensure a minimum range of unused labels if you intend to edit your solver input file manually.

6. Click Automatically Resolve .The specified offsets are applied, and the status of invalid component FEMs changes to Valid .

7. Click OK.

Resolve component FEM label conflicts manually

1. In the Simulation Navigator, right-click the assembly FEM node and choose Assembly Checks→Assembly Label Manager.

2. In the Labels group, examine the current status of component FEM labels in your assembly FEM by clicking the each of the tabs to view label status for each entity type.Conflict appears in the Status column if the component FEM's label range conflicts with other components.

3. On a tab where a conflict appears, click in the Offset cell for any component FEM and type an offset value. Press Enter or click Apply to update the table.Continue to modify the offsets until all component FEMs have a status of Valid .

4. Repeat the previous step as needed for each tab.

5. When you are satisfied with the defined offsets, click OK.

Resolve subassembly FEM label conflicts automatically

1. In the Simulation Navigator, right-click the simulation node or assembly FEM node, and choose Assembly Checks→Component Sub-Assembly Label Conflicts.

2. If conflicts exist, click Resolve in the Automatic Component Sub-Assembly Label Conflicts message box, and then review and close the Information window.If no conflicts exist, or if they exist only in the top-level component FEM files, click OK in the message box.
