For the complex task to attain maximum use and maximum security maintenance of nuclear reactors, we simulate the physical behaviour by way of mathematical models. The stationary solution of the Neutron Diffusion Equation as an eigenvalue problem, presented in this paper, results in a large non-linear partial differential equation system (PDE) whose solution is parallelized and implemented on the DIRMU multiprocessor system. We demonstrate that modern algorithms (e.g. multigrid methods) combined with innovative hardware (e.g. vector-multiprocessor systems) can lead to powerful tools which are needed for real-time simulation of physical events. This approach also allows to solve problems which arise in fluid dynamics, aerodynamics, weather forecast, etc. in a reasonable amount of time. |
