A mixed finite element approximation of the Stokes equations with the boundary condition of type ( D + N )

چکیده
In this paper we introduced the Stokes equations with a boundary condition of type (D+N). The weak formulation obtained is a problem of saddle point type. We have shown the existence and uniqueness of the solution of this problem. We used the discretization by mixed finite element method with a posteriori error estimation of the computed solutions. In order to evaluate the performance of the method, the numerical results are compared with some previously published works or with others coming from commercial code like Adina system.

A Posteriori Error Estimator for Mixed Approximation of the Navier-Stokes Equations with the Boundary Condition
In this paper, we introduce the Navier-Stokes equations with a new boundary condition. In this context, we show the existence and uniqueness of the solution of the weak formulation associated with the proposed problem. To solve this latter, we use the discretization by mixed finite element method. In addition, two types of a posteriori error indicator are introduced and are shown to give global...

متن کاملFinite element analysis of the stationary power-law Stokes equations driven by friction boundary conditions
In this work, we are concerned with the finite element approximation for the stationary power law Stokes equations driven by nonlinear slip boundary conditions of ‘friction type’. After the formulation of the problem as mixed variational inequality of second kind, it is shown by application of a variant of Babuska– Brezzi’s theory for mixed problems that convergence of the finite element approx...
متن کاملDiscontinuous Galerkin Finite Element Discretization for Steady Stokes Flows with Threshold Slip Boundary Condition
This work is concerned with the discontinuous Galerkin finite approximations for the steady Stokes equations driven by slip boundary condition of “friction” type. Assuming that the flow region is a bounded, convex domain with a regular boundary, we formulate the problem and its discontinuous Galerkin approximations as mixed variational inequalities of the second kind with primitive variables. T...
متن کاملOn a Finite Element Approximation of the Stokes Problem under Leak or Slip Boundary Conditions of Friction Type
A finite element approximation of the Stokes equations under a certain nonlinear boundary condition, namely, the slip or leak boundary condition of friction type, is considered. We propose an approximate problem formulated by a variational inequality, prove an existence and uniqueness result, present an error estimate, and discuss a numerical realization using an iterative Uzawa-type method.
