Automated hexahedral meshing

为通用3D对象自动生成高质量的体积六面体或立方体网格，从一开始就是有限元网格划分的圣杯。我们实验室开发的一个原型六角网格算法朝着这个目标取得了重大进展，比以往任何方法都能为更大范围的输入生成更高质量的网格。这项研究的目标是将这一初步原型转换为可供演示的测试版。我们特别计划简化当前的原型，完善软件设计，以强有力地支持大型输入/输出网格，并提供用户预期的功能，这些功能虽然经过充分研究，但需要与我们的框架一起实施和测试。我们还计划与我们目前的行业联系人合作，对软件进行广泛的用户测试，既在行业提供的输入上对软件进行内部测试，又提供适当的文档、用户友好的软件版本供他们在内部测试。

Quality automatic volumetric hexahedral, or cuboidal, mesh generation for generic 3D objects had been the holy grail of finite-element meshing since inception. A prototype hex-meshing algorithm developed by our lab makes significant advances toward this goal, generating better quality meshes for much wider range of inputs than any previous methodology. The goal of this research is to convert this preliminary prototype into a demo ready beta-version. We specifically plan to streamline the current prototype refining the software design to robustly support large input/output meshes, and provide user-expected features, which while well-researched, require implementation and testing in conjunction with our framework. We also plan to conduct extensive user testing of the software in collaboration with our current industry contacts, both testing the software internally on industry provided inputs, and providing a suitably documents, user-friendly version of the software for them to test in house.
