<p>Optimal spatial packaging of interconnected systems with physical interactions (thermal, hydraulic, electromagnetic, etc.), or SPI2, plays a vital role in the functionality, operation, energy usage, and life cycle of practically all engineered systems, from chips to ships to aircraft. These highly-nonlinear SPI2 problems, involving tightly constrained component packing, governed by coupled physical phenomena transferring energy and material through intricate geometric interconnects, have largely resisted design automation for decades, and can quickly exceed human cognitive abilities at even moderate complexity levels. Existing design methods treat the pieces of this problem separately without a fundamental systems approach and are sometimes too slow to evaluate various possible designs. Hence, there exists an emergent need to develop efficient SPI2 design automation frameworks for two reasons: 1) to enable the rapid generation and evaluation of candidate SPI2 design solutions; and 2) for the development of newer complex engineering systems. In this paper, the holistic 3D-SPI2 design problem with its attributes is defined, previous research efforts in various SPI2 related areas are reviewed, some existing critical gaps are outlined, and associated challenges are identified. Finally, a vision for fundamental research in SPI2 design based on the authors' experience in this topic is presented through a set of new exciting opportunities at the intersection of several engineering domains.</p>

ASME 2021 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference (IDETC/CIE2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
