The following example shows all assembly and components, including the FEMs, Assembly FEM(AFEM) and the AFEM's SIM files are at Revsion A.

Initially, comp2/A;1 is to be edited.

The model after the edit.

1. Select File -> Save -> Save As to revise comp2 CAD Part. Note the settings on the dialog.
Double Click the asterisks to revise the comp2 to the next revision

OK to complete the task

Make comp2_fem1/A;1 the work part. Note the Update Pending notification

After the Update is completed,
select File -> Save -> Save As. The Save Parts As dialog displays and the comp2_fem1 and the comp2_fem1_i(Idealized Part) are selected. 
Double Click the red Asterisks and OK to continue.

If comp1/A is edited and triggers the process to revise the CAD Assembly, Assembly FEM and associated SIM file, the workflow is the same. Note prior to this step, comp1/A, comp1_fem1_i/A and comp1_fem1/A have executed the FEM Update Pending operation. In this instance comp1/A along with the associated CAE Data will be revised in one step. Make sure all of the files that are to be revised are properly Selected. .

The resulting revisions are shown in the Simulation Navigator.

The Teamcenter list of the FEMs, AFEM and AFEM's SIM is below
