Abstract:

Systems and method for simulating liquid containment behavior. The system comprises a solid modeler and a nonlinear equation solver. The nonlinear equation solver takes as input the solid model representation of the containment vessel from the solid modeler, a desired orientation in space, dynamic conditions (e. g. , lateral acceleration) and an amount of liquid. To find the level of liquid in the vessel, the system solver iteratively performs successive Boolean subtractions using an infinite horizontal half-space that represents the liquid level of the vessel. The resulting sliced solid model is used to compute the volume of the liquid at that level. The iterative system solver terminates when the computed volume of the sliced containment vessel matches the specified volume of liquid (e. g. , fuel) within a given tolerance. To accommodate dynamic situations, e. g.

US Classification:

Abstract:

Systems and methods are disclosed for enabling users to write scripting code in a first scripting language, and then use a second scripting language to call language constructs written in that first scripting language. Functions, Class Definitions, Class Instances, Modules and other language constructs are treated as first-class objects that can be shared across the different scripting languages. The techniques disclosed herein are also applicable to domain-specific languages. As part of the methodology, a respective underlying representation of each of these object types is designed as an interface and then that interface is implemented in each scripting language. In addition, code is written in each scripting language implementation to allow the latter to use the interface to represent a Function, Class, or other language construct.
