Zusammenfassung:Methods, systems, and devices for determining construction data for producing a forming die are provided. Using an electronic computing device, a simulation is carried out that includes moving die parts of a die toward each other to a closed position, reshaping a workpiece reshaping a workpiece from an initial state to a first deformed state due to the moving of the die parts to the closed position, keeping the die parts at least temporarily in the closed state to maintain the workpiece in the first deformed state, moving the die parts away from each other to an open position, and deforming the workpiece to a second deformed state from the first deformed state due to internal stresses of the workpiece and due to moving of the die parts to the open position. A geometry of a new die part that influences the reshaping is determined.
