Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-conformal interface approaches for heat transfer simulations in complex industrial cases, such as automotive under-hood applications, are not robust due to gaps and penetration between mesh interfaces, leading to inaccurate solutions and slow convergence in computational fluid dynamics (CFD) discretization.
Innovation Solution
The implementation of a thermal coupling algorithm with non-conformal interfaces for heat transfer simulations, which involves mesh generation for different regions, determining overlapping areas between mesh faces, and discretizing total heat flow based on these areas to improve solution accuracy and convergence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional non-conformal interface approaches are used for mesh generation, then flexibility in modeling complex geometries is improved, but solution accuracy and convergence are worsened due to gaps and penetration between mesh interfaces
Solution Approach 1:
The patent introduces an intermediary computational approach that bridges the gap between non-conformal mesh interfaces. By using a thermal coupling algorithm with interface elements that act as mediators, the system transfers heat flow data between regions with non-matching meshes while maintaining accuracy. The interface elements serve as intermediaries that reconcile the geometric flexibility of non-conformal meshes with the need for accurate heat transfer calculations.
2Adaptability or versatility
If conventional non-conformal interface approaches are used for mesh generation, then flexibility in modeling complex geometries is improved, but convergence speed is worsened
Solution Approach 1:
The thermal coupling algorithm introduces intermediary interface elements that facilitate efficient data exchange between non-conformal mesh regions. These intermediaries enable the solver to converge faster by providing a structured approach to handling the interface conditions, rather than dealing with the irregular gaps and penetrations that occur in conventional approaches.
3Device complexity
If conventional mesh interface approaches are used, then implementation complexity is reduced, but processing burden and memory requirements increase due to inaccurate solutions
Solution Approach 1:
The patent introduces intermediary interface elements that, while adding some computational complexity, actually reduce the overall processing burden. By handling the interface treatment in a systematic and localized manner, the algorithm avoids the need for global mesh adjustments or iterative corrections that would consume more computational resources. The intermediaries confine the complexity to the interface region only.

AI summary
Systems and methods are provided for heat transfer simulations. Mesh generation is performed for a plurality of regions. Mesh faces are determined on different sides of an interface between the regions and overlapping areas between the determined mesh faces are determined. A total heat flow associated with the interface is discretized based at least in part on the one or more overlapping areas for heat transfer simulations.
