After the analysis is complete, you can use the Visualization module to overlay contour plots from the submodel and the global model. For a meaningful comparison, the layers of the overlay plots should use the same legend scale and the same deformation scale factor. For more information, see Chapter 53, “Overlaying multiple plots.”
You should check the following:
The submodel location
You should check that the position of the submodel is correct, relative to the the global model. You can check the relative positions using overlay plots from the global and submodel output databases. Alternatively, you can check the relative positions in the Assembly module before you submit the submodel for analysis by creating temporary instances of the parts in the global model. You can view the position of the assembly in the global model relative to the position of the assembly in the submodel. You can then delete or suppress the instances of the parts in the global model before you mesh and analyze the submodel.
The submodel response does not influence the global response
You should check that the submodel response has insignificant impact on the global response. This is the fundamental assumption of submodeling. You can check this by creating overlay contour plots of variables like stress and strain. The contours should be reasonably continuous across the submodel boundary.
