%T Solving Partial Differential equations via Cellular Automata: A Binary and Statistical Approach %A A. Cosnuau, F. Desbois, Y. Morchoisne %E J. Wexler %B OUG\-11: Developing Transputer Applications %X Cellular automata are used to solve partial differential equations (PDE) discretized on a non\-regular grid. Boolean representations of real numbers are introduced and logical intrinsic computer functions are used to achieve algebraic operations of the finite difference algorithm. In a first step the method is briefly explained and then implementation is described. For diffusion or convection problems, preliminary computations on a Cray\-XMP18 and on a network of T800 Transputers were done.
