The broader impact/commercial potential of this I-Corps project has its origins in the use of Mesh-free Monte Carlo methods as a novel technology for simulation of multi-physics, multi-scale systems. This project's mesh-free simulation approach is applied to superconducting system design. The lack of engineering tools for integrated analysis and design of superconducting coils, in particular for complex phenomena such as superconducting quench, is a bottleneck that hinders the development of reliable superconducting systems. This project addresses the design and simulation of superconducting devices, enabling reliable, computationally efficient modeling, simulation and analysis of complex phenomena such as quench in full scale systems. Mesh-free modeling tools for multi-physics analysis of multi-scale systems benefit applications where large dimensions or multi-scale geometries makes meshing computationally prohibitive.This I-Corps project involves software tools and simulation techniques for multi-physics simulation of multi-scale systems based on mesh-free Monte Carlo methods. The approach enables the computationally efficient simulation of coupled systems with multi-scale geometries where proper meshing for conventional finite element methods becomes prohibitive. The project enables a complete study of the potential commercialization of the software tools and simulation techniques being developed, as well as an assessment of technical areas and commercial applications which could benefit from the proposed approach for simulation of multi-scale systems. The project could enable simulation of multi-scale, multi-physics problems in a wide variety of potential applications based on a novel approach: mesh-free floating random walk Monte Carlo methods and may enable simulation of systems that are currently intractable using conventional finite element tools.

该I-Corps项目的更广泛的影响/商业潜力起源于使用无网状蒙特卡洛方法作为一种新型技术，用于模拟多物理，多尺度系统。该项目的无网格模拟方法应用于超导系统设计。 缺乏用于综合分析和设计超导线圈的工程工具，尤其是对于诸如超导淬火等复杂现象的瓶颈，它阻碍了可靠的超导系统的发展。 该项目介绍了超导设备的设计和仿真，从而实现了可靠的，计算有效的建模，模拟和分析复杂现象（例如全尺度系统中的淬火）。多物理分析多规模系统的无网格建模工具有益于应用应用程序，其中大尺寸或多尺度几何形状使网格划分在计算方面都令人难以置信。本I-Corps项目涉及软件工具和模拟技术，用于基于Mesh-free Monsh-Free Monte-Free Montete Carlo Carlo Carlo Carlo Carlo Carlo Carlo方法的多型物理模拟。该方法可以使用多尺度的几何形状对耦合系统进行计算有效的仿真，在这些系统中，适当的传统有限元方法的适当分类变得过于敏感。该项目可以完整研究正在开发的软件工具和仿真技术的潜在商业化，以及对技术领域和商业应用的评估，这些评估可能受益于拟议的多规模系统模拟方法。该项目可以基于新的方法来模拟多种潜在应用中的多尺度多物理问题：无网格的浮动随机步行蒙特卡洛方法，并可以启用使用常规有限元工具可在目前可纠缠的系统。
