Patent ID: 8214180

Claim:
A computer-aided method for simulation of temporal propagation of a technical process as an evolution problem, wherein the evolution problem 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 using algorithms specific to the mathematical models, the simulation being implemented using a plurality of computer calculation units, the method comprising the steps of: mapping the mathematical models on a single connected graph structure ( 1 ) with the discretisation entities as nodes ( 2 ) and producing neighbourhood relations thereof as edges ( 3 ), edges ( 3 a , 3 b ) between discretisation entities belonging to the same model and also as edges ( 3 c ) between discretisation entities belonging to different models, using at least one of the computer calculation units, for the nodes assigned to a mathematical model, for the edges ( 3 a , 3 b ) between nodes belonging to the same model and also for nodes belonging to different models, indicating specific evolution operators, using at least one of the computer calculation units, propagating the graph in time using the evolution operators, using at least one of the computer calculation units, and simulating the technical process by using the propagated graph.
