Abstract:
We describe some features of a three-dimensional numerical simulator
currently under development for studying water physico-chemical properties
during the flooding of hydroelectric plants reservoirs. The work is sponsored by
the Brazilian Electric Energy National Agency (ANEEL) and conducted with
Furnas Centrais Elétricas S. A., the leading Brazilian power utility company. An
overview of the simulator requirements is given. The mathematical model, the
software modules, and engineering solutions are briefly discussed, including the
finite element based transport module. We compare methods, iterative methods
and preconditioners used to solve the sparse linear systems which arise from the
discretization of three-dimensional partial differential equations.
