Patent ID: 7359841

Claim:
A method for predicting a resulting unsteady behavior from a manufactured or engineered component, said method comprising steps of: determining at least one governing unsteady partial differential or integral equation describing the unsteady behavior resulting from the component; determining a volume of space-time in which said unsteady behavior is to be obtained, said volume of space-time associated with a spatial geometry of the component over some period of time; discretizing the at least one equation to allow a numerical solution of the at least one equation in said space-time volume on a computational grid; generating said computational grid comprising cells or elements for at least partially filling said total volume of space-time, said cells or elements having faces which are oriented in any direction in space and time; placing said cells or elements in said total volume of space-time in such a manner so as to allow for said numerical solution, said cells or elements to be concentrated or clustered to adequately resolve the changing behavior of the component in space and time; and a computer generating data representing said prediction of the unsteady behavior by using the computer for solving said discretized at least one governing unsteady partial differential or integral equation on said computational grid, thereby providing said numerical solution; and said computer storing said data representing said prediction of the unsteady behavior, wherein said data represents the predicted unsteady behavior resulting from the manufactured or engineered component.
