We consider the problem of modeling very complex physical systems by a network of collaborating PDE solvers. Various aspects of this problem are examined from the points of view of real applications, modern computer science technologies, and their impact on numerical methods. The related methodologies include network 0/ collaborating software modules,(More)
A new approach was presented in [11] for construcling preconditioners through a function approximation for the domain decomposi~ion-based preconditioned conjugate gradient method. This work extends the approach to more general cases where grids may be nonuniform; elliptic op-eratoI'B may have variable coefficients (but are separable and self-adjoint); and(More)
