Abstract: A computer-implemented method of modelling a root-mean-square stress in a structure induced by a random load. The method comprises determining a modal correction factor based on data representing the eigensolution for the structure in free vibration. The modal correction factor characterizes the proportion of the random load, which is attributable to the root-mean-square response of the structure. Once the modal correction factor has been calculated, it is applied to data representing a stress in the structure due to a forced vibration to thereby determine the root-mean-square stress induced by the random load.

Abstract: A system and method of accelerating sparse matrix operations in full accuracy simulation of a circuit includes determining repetitive blocks of the circuit, determining a set of values of a current block, determining whether the state of the current block is sufficiently close to the state of a stored block solution when the corresponding values are within a predetermined error range, and performing a reduced computation using the stored block solution to provide a solution for the current block when the states are sufficiently close to each other. The reduced computation includes retrieving previously stored solutions and performing substantially simplified matrix and vector operations while maintaining accuracy of the solution. Reduced precision versions of the values may be used to generate a hash index used to store the block solutions. Stored redundant device information may also be used to simplify device solutions in a similar manner.

Abstract: Systems and methods of conducting a time-marching simulation of manufacturing a sheet metal part that requires progressive lancing operation (PLO) are disclosed. The time-marching simulation is conducted with a connection-separation scheme for nodes along the lancing route to ensure a smooth timely separation of a lancing cut. The scheme includes creating a set of surrogate lancing route nodes by duplicating nodal coordinates of the existed nodes located along the lancing route. Nodal constraints to initially link together the existed nodes and the corresponding surrogate nodes are then created. The nodal constraint is removed in accordance with a separation time schedule established using start and end locations of the lancing route and corresponding start and end time for making the lancing cut. The nodal constraints can also be removed based on the zones of the lancing route defined by a user.

Once configured, the safety automation builder can export the safety function data to an external verification system for confirmation that the configured safety functions comply with the prescribed industrial safety standards.

Abstract: A method and apparatus that allows the user of a computer aided design (CAD) system to connect three-dimensional parts to create a three-dimensional assembly using connections that completely define the attachment between the parts attached to each other by that connection. The user can simultaneously define the orientations of the parts and their behavior. “Behavior” includes whether parts are rigidly connected or allowed to move relative to one and other, and if allowed to move, the nature and limits on that movement. Within any movement allowed, the user may specify key discrete orientations known to be important to the function of the assembly, such as orientations that limit movement within the assembly. The connection method creates a smaller, more consistent representation of the underlying constraints of the assembly, improving the reliability, performance, and ease of use of a CAD system in which it is used.

Abstract: This invention relates to a method of designing an illumination device, wherein a light source unit is modeled with a set of rays. Therein, each ray is assigned a light power and is further characterized by a light volume, which specifies how “spread out” the light is in area and angle. In this way, a selection of rays with respect to their “density” becomes possible, and an optical system can be optimized for a transmission of those rays providing the most light per volume.
