AB - In this paper, we consider a Stokes problem arising in fluid dynamics and  thermal science, which can be transformed to a symmetric saddle point  problem by using the mixed finite element approximation. A relaxed  non-linear inexact Uzawa algorithm is proposed for solving the problem, and  the convergence of this algorithm is also considered. Numerical experiments  are presented to show the efficiency of relaxed non-linear inexact Uzawa  algorithm.
