This project develops the first high-fidelity aerodynamic virtual human model to support the scientific community and to tackle various emerging public-health problems. The proposed collaborative research addresses the significant and numerous computational challenges associated with the modeling and simulation of dynamic virtual human systems, involving aerodynamic flow processes and various physical components (e.g., face, hair, clothes, crowd, and thermal environments). The specific focus here is on modeling the human's aerodynamic micro-environment and its interactions with human respiratory activities, which have largely been neglected in the virtual human literature. The research aims are: (1) model the aerodynamic microenvironment consisting of thin layers of airflow near the boundary of human face; (2) simulate contact, friction, and solid-air coupling with areas of the human body, including skin, hair, and clothing surfaces; and (3) develop numerical algorithms to model aerodynamic crowds for multi-physics and multi-agent simulation. Among these aims, differentiable numerical solvers will be developed to facilitate optimization and computational design for human respiration-related problems.The proposed algorithms will introduce a new family of computational tools based on first principles to fill the gaps in simulation, animation, design, and education regarding the previously ignored aerodynamic subarea of virtual human modeling. The PIs will also disseminate the results as open-source software libraries and databases of simulation results. If successful, the availability of these aerodynamics-aware virtual human models, augmented by an ensemble of differentiable physics simulators, individualized data models, interactive visualization, and VR/AR display, can provide convenient and intuitive tools for various applications that involve the human form.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目开发了第一个高保真空气动力虚拟人类模型，以支持科学界并解决各种新兴的公共卫生问题。提出的协作研究旨在解决与动态虚拟人类系统的建模和模拟相关的重大计算挑战，涉及空气动力学流动过程和各种物理组件（例如，面部，头发，衣服，人群，人群和热环境）。这里的具体重点是建模人类的空气动力学微环境及其与人类呼吸活动的相互作用，这些环境在虚拟人类文献中很大程度上被忽略了。研究目的是：（1）模拟空气动力学微环境，该环境由人脸边界附近的薄层气流组成； （2）模拟接触，摩擦和固体空气与人体区域，包括皮肤，头发和衣服表面； （3）开发数值算法，以建模用于多物理和多代理模拟的空气动力学人群。在这些目标中，将开发可区分的数值求解器，以促进与人类呼吸有关的问题的优化和计算设计。拟议的算法将基于第一个原理介绍一种新的计算工具系列，以填补有关以前忽略的虚拟人类模型的模拟，动画，设计和教育的空白。 PI还将作为开源软件库和模拟结果数据库传播结果。 If successful, the availability of these aerodynamics-aware virtual human models, augmented by an ensemble of differentiable physics simulators, individualized data models, interactive visualization, and VR/AR display, can provide convenient and intuitive tools for various applications that involve the human form.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
