摘要

虽然交互式仿真大多局限于计算机图形应用，但新一代图形处理器（GPU）允许实现工业级交互式三维物理仿真。通过将沉浸边界法与基于 GPU 的 MINRES 和 CG 求解器（使用基于 GPU 的几何多格预处理器）高效结合，我们展示了一种快速的工业级三维计算力学求解器。我们详细讨论了各种实现方面，特别是它们与计算机图形学界使用的类似概念有何不同。所提出的概念开辟了新的工业仿真应用领域，使其超越了当今的专家用户，从以设计师为中心的仿真到基于三维仿真的运营和服务决策，实现了民主化。为了证明这一点，我们提供了各种基准案例，包括对损坏的变速箱支架进行基于仿真的服务决策的实际研究。

Fast 3D solvers for interactive computational mechanics

While interactive simulations have been mostly limited to Computer Graphics applications, new generations of Graphics Processing Units (GPUs) allow the realization of industrial-grade interactive 3D physics simulations. By combining an immersed boundary method with efficient GPU-based MINRES and CG solvers using a GPU-based geometric multigrid preconditioner, we demonstrate a fast industrial 3D computational mechanics solver. The various implementation aspects - specifically how they differ from similar concepts used in the Computer Graphics community - are discussed in detail. The proposed concept opens up new classes of industrial simulation applications allowing a democratization beyond today’s expert users, from designer centric simulation to operational and service decisions based on 3D simulations. To support this, we provide various benchmark cases including a real-world study of a simulation-based service decision for a damaged gear-box mount.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
