In this study we consider parallel conjugate gradient solution of sparse systems arising from the least-squares mixed finite element method. Of particular interest are transport problems involving convection. The least-squares approach leads to a symmetric positive system and the conjugate gradient
The Preconditioned Conjugate Gradient algorithms (PCG) are used for solving the matrix equations arising from the Finite Element Method (FEM) with high-order element functions. A vectorizable and a non-vectorizable block preconditioner for use with the conjugate gradient method is presented. The alg
