WebJul 31, 2015 · This paper deals with the analysis of new mixed finite element methods for the Brinkman equations formulated in terms of velocity, vorticity and pressure. Employing the Babuška–Brezzi theory, it is proved that the resulting continuous and discrete variational formulations are well-posed. WebNov 19, 2024 · The resulting continuous and discrete schemes, whose only unknowns are given by the Cauchy fluid stress, the velocity of the fluid, and the concentration, are analyzed by means of a fixed-point strategy that …

We discuss the application of Virtual Elements to linear plate bending problems, in the Kirchhoff–Love formulation. As we shall see, in the Virtual Element environment the treatment of the C 1 -continuity condition is much easier than for traditional Finite Elements. The main difference consists in the fact that traditional Finite ... hawthorne manor west bend wi
