Hierarchical basis for stabilized nite elementmethods for compressible owsChristian

چکیده

The quest for more accurate numerical simulations of the Navier Stokes equations has motivated the study of high-order piecewise-polynomial basis functions, also known as k-version nite element methods, as a means to attain this accuracy in the most cost eeective manner. Stabilized nite element methods (e.g. SUPG) have been proven to attain optimal rates of convergence for any polynomial order basis as well as perform well on a variety of ows including turbulence applications. We present a stabilized nite element formulation for uid dynamics using mesh-entity based hierarchical basis functions. The implementation is shown to attain theoretical convergence results for the linear model problem as well as the Navier-Stokes equations.

Hierarchical Bases and the Finite Element Method

The choice of basis functions for a nite element space has important consequences in the practical implementation of the nite element method. A traditional choice is the nodal or Lagrange basis. Many of the computational advantages of this basis derive from the property of compact support enjoyed by the basis functions. Here we study a second choice, the hierarchical basis, and examine its appl...
