Abstract: Embodiments of the present invention relieve the burden on a product designer to setup simulations to validate a product design. These embodiments are directed to computer methods and systems for inverting a simulation process to validate a product design. The methods and systems configure a simulator with analysis methods. The methods and systems then provide product design parameters (operating environment conditions and design targets) that define scenarios likely experienced by a product in terms familiar to the product designer. The methods and systems, via the simulator, automatically determine simulations for validating the product design based on the provided product design parameters. To do so, the methods and systems map each of the design parameters to one or more analysis types, which are used by the simulator to select a sequence of analysis methods to define the simulations. The methods and systems execute the simulations to validate the product design.

Abstract: The present invention relates to a method and system for performing a finite element simulation. Embodiments of the present invention determine accurate contact simulations. A method according to the principles of the present invention begins by obtaining a first finite element model and a first computer aided design (CAD) model that the first finite element model represents. Next, a finite element simulation is performed using at least the first finite element model and the first CAD model. According to an embodiment of the present invention, performing the finite element simulation comprises determining one or more variations between the first finite element model and the first CAD model.

Abstract: A computer-implemented method and system automatically detects stress singularity in a three-dimensional (3D) computer-aided design (CAD) model. A potential area of high stress is detected. A finite element mesh of the 3D CAD model is refined, at least in the potential area of high stress, after which, whether the high stress value converges is determined. A user is alerted that the potential area of high stress is an area having one or more elements of stress singularity. Suggestions are made regarding how to eliminate the stress singularity and the user is enabled to modify the design of the 3D CAD model to eliminate the stress singularity.

Abstract: A method, according to an embodiment, provides a simulation of a physical real-world system, by first generating a system of equations that includes a discrete representation of the real-world system being simulated. Next, the real-world system is simulated. In simulating the system, a user specified tolerance of a solution of the system of equations is obtained. Then, the system of equations is iteratively solved until a solution to the system of equations for a given iteration is within the user specified tolerance of the solution of the system of equations for approximately infinite iterations. In such an embodiment, the solution to the system of equations for the given iteration is determined to be within the user specified tolerance using an experimentally determined constant, an estimate of a minimum eigenvalue of the system of equations for the given iteration, and a residual of the system of equations for the given iteration.

Abstract: A method of executing a simulation model while generating an associated structural model includes changing, by a computer-aided design (CAD) system, the structural model. The method further includes evaluating, by the CAD system, at least one trigger criterion to determine if the change to the structural model is a simulation trigger event. The method also includes executing, by the CAD system, the simulation model if the change to the structural model is determined to be the simulation trigger event.
