Abstract

An algorithm is suggested to improve the efficiency of the multi-level Newton method that is used to solve multi-physics problems. It accounts for fulll coupling between the subsystems by using the direct differentiation method rather than error prone finite dilfference calculations and retains the advantage of greater flexibility over the tightly coupled approaches. Performance of the algorithm is demonstrated by solving a fluid-structure interaction problem.
