SBIR Phase II: A Toolbox for Optimal Design

这个小型企业创新研究（SBIR）第二阶段项目将波传播现象的大规模模拟与优化相结合。 模拟本身很少是最终目标。 相反，模拟通常是解决真实的问题的迭代过程中的一个步骤，这可能是通过间接测量、成像、参数估计或最佳设计来确定材料特性，仅举几例。 所有这些问题都需要将大型仿真包与优化包耦合起来。 该项目将正式确定这一概念，并着手创建一套工具，以促进瞬态波传播现象领域的这种耦合，特别是压电换能器设计，石油勘探和生产，以及优化和保护结构设计。 选择这些应用程序是为了说明工具箱的用法并强调其通用性。 它将耦合一个波传播有限元系统和一个系统的三维正演和反演地质建模，与一些优化programmes.The目标市场的建议解决方案是中小型公司需要一套负担得起的设计工具，将覆盖一些不同类别的应用领域，以前只有大公司提供。 该项目的结果将对大量依赖计算机辅助设计和工程开发产品的中小型行业产生广泛影响，加速并提高产品概念，生产和市场引入之间的过程，这是竞争激烈的世界的关键。

This Small Business Innovation Research (SBIR) Phase II project combines large-scale simulation of wave propagation phenomena with optimization. Simulation in itself is seldom a final objective. Rather, simulation is usually a step in an iterative process to solve the real problem, that could be the determination of material properties from indirect measurements, imaging, parameter estimation or optimal design, to name a few. All these problems share the need to couple a large simulation package with an optimization one. This project will formalize this concept and proceed to create a set of tools to facilitate this coupling in the area of transient wave propagation phenomena, with special applications to piezoelectric transducer design, oil exploration and production, and optimal and protective structural design. These applications are chosen to exemplify the usage of the toolbox and emphasize its generality. It will couple a wave propagation finite element system and a system for 3D forward and inverse geological modeling, with a number of optimization programs.The target market for the proposed solution is small to medium sized companies in need of a set of affordable design tools that will cover a number of different classes of application areas which have been previously available only to large firms. The results of this project will have a broad impact on a large number of small and medium size industries that rely on Computer Aided Design and Engineering to develop their products, accelerating and making more efficient the process between product conception, production and market introduction, key in a highly competitive world.
