摘要
A coupled nonlinear elliptic system modelling a large class of engineering problems is studied. Existence, uniqueness and regularity of weak solutions are established. Finite element approximations combined with a a fixed point algorithm are proposed and analysed. Numerical results are presented to confirm he estimates and to illustrate the behavior of the solution close to stability limits.
