Submodeling

Submodeling can be accomplished using v14 5 without the need for Submodeling can be accomplished using v14.5 without the need for Command Blocks in Mechanical.

The global model can be copied in the same project and the submodelsections can be extracted from itsections can be extracted from it.

16

Submodeling Example

Begin with an analysis system of the global (full) model: Begin with an analysis system of the global (full) model:

17

Submodeling Example

To create the submodel analysis system RMB click on the Geometry row To create the submodel analysis system RMB click on the Geometry row of the global system and choose Duplicate.

18

Submodeling Example

Note that by duplicating from the Geometry row that the geometry of the Note that by duplicating from the Geometry row that the geometry of the duplicate system is not linked to the original and can be edited.

Rename the duplicate system to submodel.

19

Submodeling Example

Edit the geometry of the duplicate system to extract the submodel from the Edit the geometry of the duplicate system to extract the submodel from the original geometry using slicing and cutting operations. Note: Using the original geometry to create the submodel guarantees that the global model and the submodel will be spacially consistentthe global model and the submodel will be spacially consistent.

20

Submodeling Example

Edit the Model row of the submodel system to open it in Mechanical Edit the Model row of the submodel system to open it in Mechanical. Remove any boundary conditions that were copied over from global model

and do not apply to the submodel.

21

Submodeling Example

Return to the Project Page and drag the Solution row of the global model Return to the Project Page and drag the Solution row of the global model and drop it onto the Setup row of the submodel.

RMB click on the Setup row of the submodel to refresh it.

22

Submodeling Example

Return to submodel Mechanical window Return to submodel Mechanical window. RMB click on the Submodeling (Solution) item and insert Displacement.

Note that temperatures can also be interpolated.

23

Submodeling Example

Scope the geometry selection of the Imported Displacement item to the Scope the geometry selection of the Imported Displacement item to the cut boundaries of the submodel.

RMB click on the Imported Displacement item and select Import Load.Generate the s bmodel sol tion Generate the submodel solution.

24

Submodeling Example

Results can be compared at the cut boundary locations by exporting data Results can be compared at the cut boundary locations by exporting data. If the cut boundary surfaces do not exist in the global model you can

scope the result to a surface using Construction Geometry. In this case the surface data was exported from the global model and sorted in In this case the surface data was exported from the global model and sorted in MS Excel based on radial and angular location to compare with the edge results from the submodel.

25

Submodeling Example

After you are satisfied with the cut boundary locations you can evaluate After you are satisfied with the cut boundary locations you can evaluate the local submodel results.
