    • A system for adaptive partitioning of circuit components during simulating of a circuit having a hierarchical data structure includes a simulator module having one or more computer programs for 1) selecting a group of leaf circuits from the first branch and the second branch for simulation, where each leaf circuit is represented by a matrix comprising a set of equations, 2) determining a strength of coupling between two or more leaf circuits of the group in accordance with a set of predetermined electrical coupling criteria, 3) if two or more leaf circuits are deemed be strongly coupled, combining the corresponding matrix of each strongly coupled leaf circuit into a combined matrix, and 4) performing computation for the two or more strongly coupled leaf circuits in accordance with the combined matrix. The system adaptively adjusts the group circuit matrix for computing a group of circuits according to the strength of coupling between the circuits. Hence, it achieves higher simulation performance by reducing either the size of the solver matrix when the circuits are loosely connected to each other, or by reducing the number of computational repetitions due to the communication of changes of signal conditions between circuits by combining the individual circuit matrices when such circuits are closely coupled to each other.

    • A drive train of a motor vehicle includes a gear arrangement with at least two gear elements moveable relative to one another acts in a torque transmission path between an internal combustion engine and a transmission. The gear arrangement being connected between a drive-side flywheel mass and a gear-side flywheel mass. The gear arrangement includes at least one additional mass having a center of gravity (Sp) which is displaceable radially in relation to an axis of rotation (D) of the torque transmission path as a function of a relative position of the at least two gear elements. In the event of a change in the relative rotary angle between the flywheel masses, a moment of inertia of the torque transmission path also changes, so that there is no definite resonant point and the torque transmission path takes effect as a self-steadying system. Furthermore, the additional mass may be arranged to generate a centrifugally dependent return force directed toward a specific relative rotary angle position. The force acts between two rotary parts rotatable at least to a restricted extent relative to one another and located in the torque transmission path. The specific relative rotary angle position lies between two relative rotary angle boundary positions delimiting a relative rotary angle range of the rotary parts. The gear arrangement may be arranged in a two-mass flywheel or a hydrodynamic clutch device in the motor vehicle drive train.
