SUMMARY
An algorithm is suggested to improve the e ciency of the multi-level Newton method that is used to
solve multi-physics problems. It accounts for full coupling between the subsystems by using the direct
di erentiation method rather than error prone ˙nite di erence calculations and retains the advantage of
greater exibility over the tightly coupled approaches. Performance of the algorithm is demonstrated by
solving a uid­structure interaction problem. Copyright ? 2003 John Wiley & Sons, Ltd.
KEY WORDS: multi-physics analysis; uid­structure interaction; multi-level Newton method
