Piecewise linear approach to the Stokes equations in 3 D
A least-squares method for three-dimensional problems is proposed. This method leads to a minimization problem and thus it is not subject to the restriction of the Ladyzhenskaya-Babuska-Brezzi condition. Piecewise linear elements can be applied for the approximation functions; the simplest and natural elements are easy to program and achieve optimal rates of convergene.
