The invention relates to a method for computer-aided simulation of technical processes. Methods of this type are required in particular in evolution simulation models of technical, in particular physical and/or chemical processes, which are intended to be propagated in time (evolution). The method according to the invention 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 discretization 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, is characterized in that the mathematical models are reproduced on a single coherent graph structure (1) with the discretization entities as nodes (2) and the neighborhood relations thereof as edges (3), edges (3a, 3b) being produced between discretization entities belonging to the same model and also edges (3c) between discretization entities belonging to different models, respectively for the nodes assigned respectively to one mathematical model, for the edges (3a, 3b) 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.
