The paper deals with formulation and numerical realization of fluid flow problems with threshold boundary conditions. This means that the slip of the fluid on the boundary may occur only when the shear stress attains a certain bound given a-priori. The mathematical model leads to an inequality type problem. A short comment on the numerical method used for solving such problems and results of several model examples will be presented.
