9. Based on AVS/Express 5.0 built both connecting and customizing appropriate AVS components and developing some new modules developed on SGI Onyx2 platform ported on PC cluster running Linux and compiled with LessTif freeware library

10. It assists the user allowing the visualization, while editing, of the binary input files required by the bioremediation simulation. It supports the definition of the automaton general characteristic (dimensions, cell sizes, the real time to be simulated ….). It permits to prepare all those files defining the state of each cell ( substates), providing the modalities to represent both homogeneous cell array and discontinuities like surfaces and lateral walls, injection and extraction wells. It allows to import binary files coming from platforms with incompatible binary formats.
