PIFISS Software Package
Potential (Incompressible) Flow & Iterative Solver Software
Released 7 February 2007
This is an open-source
software package. It is associated with the
Uncertainty quantification in computer
simulations of groundwater flow problems with
emphasis on contaminant transport.
The PIFISS software can be used to generate typical linear systems arising
from deterministic finite element discretizations of two important PDE applications:
(variable) diffusion and potential flow. Mesh generation is done
using FEMLAB. For potential flow, discretization is with the
lowest order Raviart-Thomas mixed approximation method.
The package has built-in algebraic multigrid and Krylov subspace solvers and
appropriate preconditioning strategies for each problem.
PIFISS has been developed using Femlab 3.1 and Matlab Version 7.1 and it can be run
under Windows, Unix and Mac architectures.
