摘要
According to a preferred embodiment, the present invention provides a computing device and method to efficiently predict material behavior and to minimize the computational resources needed to obtain accurate simulations. According to a further preferred embodiment, the present invention tracks the history of driving variables for a section of a modeled element/object, for each material point or integration point or constitutive model. According to a further preferred embodiment, the present invention only maps unique histories of driving variables, within certain tolerance, to actual integration points' and/or constitutive models' data structure in order to optimize the amount of data needed to model the entire modeled element/object under determined boundary conditions. According to a further preferred embodiment, the present invention thereafter dynamically links the material response to each integration point and/or constitutive model in the modeled element/object. According to a further preferred embodiment, the present invention further balances the analysis work load across available computational resources to provide maximized performance. According to a further preferred embodiment, the present invention further reduces computational requirements through the use of databases to store/retrieve results obtained for a given history of driving variables and material definition.
