Existing physical artifacts, including sculpture, mechanical parts, and anatomical structures, are commonly acquired by modern surface and volumetric scanning technologies for archival, visualization, and diagnostic purposes. Using recently developed meshfree technology, PIs established feasibility of performing engineering analysis directly on acquired geometry, bypassing tedious, error-prone, and artificial reconstruction methods. This proposal calls for a thorough investigation of the potential of this exciting technology by addressing basic accuracy and resolution issues, efficient implementation and complete automation of all steps, application of the technology to selected applications, and careful validation of the results. A successful outcome of the proposed research will result in a breakthrough technology for performing rapid engineering analysis on physical artifacts in situ. Rapid growth and adoption of acquired and digitized data in design, manufacturing, and engineering at large underscores the significance of the proposed research. More broadly, the proposed research will lead toward next generation systems where designed and acquired geometric information is integrated with physical models and are treated in a common computational framework. This holds the promise of extending the benefits of traditional CAD/CAE tools to works of art and architecture, biomedical applications, reverse engineered models, as well as complex assemblies and systems.

现有的物理伪影，包括雕塑，机械部件和解剖结构，通常通过现代表面和体积扫描技术获取，用于存档，可视化和诊断目的。使用最近开发的无网格技术，PI建立了直接对采集的几何结构进行工程分析的可行性，绕过了繁琐、容易出错的人工重建方法。该提案要求通过解决基本的精度和分辨率问题，有效实施和所有步骤的完全自动化，将该技术应用于选定的应用程序，并仔细验证结果，对这项令人兴奋的技术的潜力进行彻底的调查。拟议研究的成功结果将导致在现场进行物理文物的快速工程分析的突破性技术。在设计、制造和工程中获得和数字化数据的快速增长和采用强调了拟议研究的重要性。更广泛地说，拟议的研究将导致下一代系统，其中设计和获取的几何信息与物理模型相结合，并在一个共同的计算框架中处理。这有望将传统CAD/CAE工具的优势扩展到艺术品和建筑、生物医学应用、逆向工程模型以及复杂的装配和系统。
