You should check the following:
- The submodel
location
-
You should check that the position of the submodel is correct, relative to
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.
