When you run the Abaqus component, Isight runs background sessions of CATIA V5 and Abaqus/CAE. The Abaqus component extracts the value of the CATIA V5 geometry parameters from CATIA V5 and makes them available to Isight.
Note:
If you do not select Extract CATIA V5 parameters, the Abaqus component does not extract geometry parameters from CATIA V5 into Isight. Abaqus/CAE parameters, such as loads and stresses will still be available to Isight; however, a background session of CATIA V5 will not be launched during runtime because there are no CATIA V5 geometry parameters to update.
