1. Method for computer-aided simulation of the temporal propagation of technical processes as evolution problem, which is described by at least two different mathematical models as sub-evolution problems which use discretisation entities which are different from each other and are propagated in time by means of model-specific algorithms, the simulation being implemented by means of a large number of calculation units, characterised in that the mathematical models are reproduced on a single coherent graph structure ( 1 ) with the discretisation entities as nodes ( 2 ) and the neighbourhood relations thereof as edges ( 3 ), edges ( 3 a , 3 b ) being produced between discretisation entities belonging to the same model and also edges ( 3 c ) between discretisation entities belonging to different models, respectively for the nodes assigned respectively to one mathematical model, for the edges ( 3 a , 3 b ) between nodes belonging to the same model and also for nodes belonging to different models, respectively specific evolution operators being indicated, and the graph being propagated in time using these evolution operators.
