The almeth project zoom code: results and perspectives

The TEF (Transfer Evolution Formalism) and the ZOOM software (Zone Organized Optimal Modelling) have been developped in order to give a flexible framework for physics oriented modelling. Their construction is based on a clear statement of the necessary partition ning/interfacing process, which leads to the definitions of the two classes of simulation objects : cells (elementary physical systems) and transfers (interfacing cells). This structure is the basis for system nesting and coupling analysis implementation. The desired flexibility is obtained through user oriented languages structured in layers following the ALMETH world-layer grid. Further adaptability will be brought up by present new tool development : time nesting, asymptotic analysis, and steady state computation. TEF and ZOOM evolution in the forthcoming years shall be concerned with the application of ZOOM to experiment analysis, the implementation of parallel processing taking advantage of the tree structure of TEF, and the opening of new physics modelling fields.
