Claim:
A data processing system for simulating at least one of tools and processes for manufacture of formed metal parts, wherein the data processing system comprises: a simulator and memory for implementing a method for simulation of a least one of tools and processes for manufacturing of formed metal parts and for providing statistical information on the simulation results, in which, from a set of nominal simulation parameters (d,n) through simulation of a metal forming process, raw data (r) for description of a geometry and of a condition of a formed metal part are calculated, the raw data (r) describing a geometry and a condition of a formed metal part in calculation points of a finite element model, the method for simulation including the steps of: calculating and saving through simulation of the metal forming process a set of raw data from the set of nominal simulation parameters (d,n) in a simulation run ( 5 ) and storing the set of raw data in the memory, the raw data (r) describing local values of the condition of the formed metal part in a multitude of calculation points which are integration points or nodal points of the finite element model, repeating the step of calculating and saving through simulation of the metal forming process more than two times, with variation of the simulation parameters (d,n) around the nominal simulation parameters (d,n), so as to generate and save further sets of raw data (r), the raw data (r) describing local values of the condition of the formed metal part in a multitude of the calculation points, statistically analyzing, for each of the multitude of the calculation points, a plurality of the saved sets of raw data (r) and thereby calculating statistical characteristic values (Cr) of the raw data (r) for the multitude of calculation points, and associating each statistical characteristic value (Cr) with a point of the geometry of the formed metal part, generating a visual depiction of at least one of the statistical characteristic values (Cr) of the raw data (r) on a visual depiction of an object involved in the metal forming process, wherein the step of statistically analyzing a plurality of the saved sets of raw data (r) comprises the steps of: assigning, for the calculation points, the raw data of the individual simulations to one another by assigning calculation points that are at the same location in space or are located closest together to one another, determining the statistical characteristic value of the raw data by statistically evaluating the raw data of the calculation points that are assigned to one another.
