About this opportunity
The Department of Energy has issued a Special Notice related to a licensing opportunity for a new hybrid explicit-implicit finite element (FE) numerical method designed to accelerate the simulation of large-scale transient thermomechanical processes such as welding and additive manufacturing. This novel algorithm combines implicit and explicit simulation approaches, allowing it to automatically switch between the two for improved accuracy while still scaling up to handle complex, large-scale problems.
The purpose of this Special Notice is to make this new hybrid FE method available for licensing by interested parties. The method is intended to significantly reduce computational time for simulating transient thermomechanical processes, which is crucial for industries like additive manufacturing and welding. The Special Notice provides a deadline of October 26, 2024 for submitting inquiries, and interested parties are invited to contact the Department of Energy to learn more about the technology and licensing opportunities.
Notice text
Invention Reference Number: 202405606
Finite element (FE) numerical computation method is widely used to facilitate the design and optimization of manufacturing processes using two types of solvers, implicit and explicit. The implicit solver is difficult to handle very large-scale problems due to the complexity to solve a large matrix of equations. The explicit solver has a requirement of a very small time increment. This technology is a novel hybrid explicit-implicit FE numerical method designed to accelerate simulation of very large-scale transient thermomechanical processes such as welding and additive manufacturing.
Description
This technology is a new algorithm for a new hybrid approach for thermomechanical processes such as welding and additive manufacturing. This combines two approaches, implicit and explicit simulation. The code can automatically switch from one to another for accuracy prediction, and still can scale up. The algorithm is designed to run on today’s GPU-based high performance computers, drastically reducing computational time while yielding good results for a large class of transient thermomechanical processes characterized by numerous heating and cooling cycles such as multi-pass welding and additive manufacturing of metallic structures.
Benefits
