چکیده
The main core of this report is to explore the functionality of IFISS package [1]. IFISS stands for Incompressible Flow Iterative Solution Software (IFISS) designed in Matlab by David J. Silvester [2], Howard C. Elman [3] and Alison Ramage [4]. IFISS comprises of discretization and solving schemes for four type of PDEs (Poisson, Convection diffusion, Stokes and Navier Stokes equations) . All these schemes along with problem specifications are explored in this report.

This paper studies a new preconditioning technique for sparse systems arising from discretized partial differential equations (PDEs) in computational fluid dynamics (CFD), which exploit the multilevel sequentially semiseparable (MSSS) structure of the system matrix. MSSS matrix computations give a data-sparse way to approximate the LU factorization of a sparse matrix from discretized PDEs in li...
متن کاملEST MINRES: An Optimal Iterative Solver for Symmetric Indefinite Systems stemming from Mixed Approximation
We discuss the design and implementation of a suite of functions for solving symmetric indefinite linear systems associated with mixed approximation of systems of PDEs. The novel feature of our iterative solver is the incorporation of error control in the natural “energy” norm in combination with an a posteriori estimator for the PDE approximation error. This leads to a robust and optimally eff...
