The objective of this research program is the development of reliable, high-accuracy and high-resolution biolectromagnetics (BIOEM) simulators that can effectively utilize petascale computational resources to quantify the interaction of the human body with nearby wireless devices. The investigators are developing two classes of advanced BIOEM solvers based on finite- and boundary-element algorithms to solve coupled electromagnetic and bio-heat transfer equations. The investigators are, also, deploying the resulting solvers on petascale computers for high-fidelity simulations and cross-validating and verifying the two classes of solvers during development to build confidence in the legitimacy of the new simulation results.This project aims to significantly advance the state-of-the-art in BIOEM simulation, to accurately model wave interactions with the human body at resolutions never before attempted, to quantify the heating effect of wireless devices on the human body and the electromagnetic effect of the human body on device performance, and to demonstrate that results from these simulations can be used to design safer and more efficient devices. It is being executed by an interdisciplinary team of researchers at the University of Texas at Austin?s Institute for Computational Engineering and Sciences and the Texas Advanced Computing Center. The resulting petascale finite- and boundary-element solvers are expected to be useful for many other wave propagation/absorption problems. The project is training students and postdoctoral researchers and establishing an interdisciplinary community of developers and users fluent in petascale computing. The investigators are introducing petascale algorithmic concepts, programming techniques, simulators, and applications into graduate and undergraduate courses. They are disseminating their findings and broadening participation of underrepresented groups through international conferences and peer-reviewed journals, through seminars at nearby universities in Texas, including those with significant underrepresented minority populations, and by releasing the resulting software via open source mechanisms.

该研究计划的目标是开发可靠，高精度和高分辨率的生物电磁学（BIOEM）模拟器，可以有效地利用千万亿次计算资源来量化人体与附近无线设备的相互作用。 研究人员正在开发两类基于有限元和边界元算法的高级BIOEM求解器，以求解耦合的电磁和生物传热方程。 研究人员还将在千万亿次计算机上部署由此产生的求解器进行高保真模拟，并在开发过程中交叉验证和验证两类求解器，以建立对新模拟结果合法性的信心。该项目旨在显着推进BIOEM模拟的最新技术，以前所未有的分辨率准确模拟波与人体的相互作用，量化无线设备对人体的加热效应和人体对设备性能的电磁效应，并证明这些模拟结果可用于设计更安全、更高效的设备。 它是由德克萨斯大学奥斯汀分校的一个跨学科研究小组执行的？计算工程与科学研究所和德克萨斯州高级计算中心。 由此产生的千万亿次有限元和边界元求解器预计将是有用的许多其他波的传播/吸收问题。 该项目正在培训学生和博士后研究人员，并建立一个由精通千万亿次计算的开发人员和用户组成的跨学科社区。 研究人员正在将千万亿次算法概念、编程技术、模拟器和应用程序引入研究生和本科生课程。 他们正在通过国际会议和同行评审期刊，通过在德克萨斯州附近的大学举办研讨会，包括那些少数民族人口代表性严重不足的大学举办研讨会，以及通过开放源码机制发布由此产生的软件，传播他们的研究结果，扩大代表性不足的群体的参与。
