SBIR Phase II: Visualizing Arbitrary Basis Functions for Advanced Engineering Analysis and Simulation

这个小型企业创新研究第二阶段项目将创建通用软件工具，用于可视化高级数值模拟的结果。仿真技术在数十亿美元的CAD/CAM/CAE市场中占很大一部分，广泛用于设计和制造当今制造的大多数产品。可视化在这个过程中起着重要的作用，它将模拟结果转换为设计师、工程师和科学家可以用来理解和交流他们的产品的图像。数值模拟的最新进展为基于高阶基函数的方法提供了机会。 这些函数更好地模拟弯曲的几何形状，并且比采用线性近似函数的传统技术更准确。由于缺乏用于高阶方法的通用可视化软件工具，这种技术的使用受到限制。提供这些工具将加速该技术在市场上的采用，从而产生能够在更短的时间内以更低的成本产生上级产品设计的软件。提出了一种自适应镶嵌过程，将高阶基转换为线性图形基元，并保持解决方案的视觉精度，同时保持交互式图形性能。这项技术将获得许可证，并将提供附加适配器，使供应商能够轻松有效地将其系统与这项技术连接起来。

This Small Business Innovative Research Phase II project will create general-purpose software tools for visualizing the results of advanced numerical simulation. Simulation techniques, which make up a large part of the multi-billion dollar CAD/CAM/CAE market, are widely used to design and build the majority of products manufactured today. Visualization plays an important role in this process by transforming simulation results into images which designers, engineers, and scientists can use to understand and communicate about their products. Recent advances in numerical simulation provide an opportunity for methods based on higher-order basis functions. These functions better model curved geometry and are more accurate than conventional techniques employing linear approximation functions. The use of this technology is limited by a lack of general-purpose visualization software tools for higher-order methods. Providing these tools will accelerate the adoption of this technology into the marketplace resulting in software that will produce superior product designs, in shorter time, and at lower cost. An adaptive tessellation process that converts higher-order basis into linear graphics primitives and preserves the visual accuracy of the solution, while maintaining interactive graphics performance, is proposed.This technology will be licensed and add-on adaptors will be offered that will enable vendors to easily and efficiently interface their systems to this technology.
