On the pressure Poisson equation for the Stokes system
Abstract: For the numerical solution of the pressure Poisson equation, we consider an ultra–weak variational formulation and a related finite element method of Galerkin–Petrov type. While this allows a piecewise constant approximation of the pressure, the test functions have to be sufficiently smooth – in particular, we use modified B–splines of second order to guarantee conformity and stability, and optimal convergence. This novel formulation allows the computation of the pressure from either a given, measured, or precomputed velocity field as it appears in many applications in fluid mechanics.
