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.

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.

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.

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.

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.

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.
