NEMoSys: A Platform for Autonomous Mesh Refinement and Solution Verification
The primary objective of this SBIR project has been to mature and harden the methodologies, algorithms, and prototype software built for AMR and solution verification with application in nuclear modeling and simulation. To make this possible, a number of additional capabilities were embedded into the IR NEMoSys package, including the means for mesh generation, solution transfer, and mesh quality assessment. To the greatest extent possible, the IR development team leveraged currently available open-source tools for the building of NEMoSys, while maintaining focus on making these tools simpler to use through a unified interface. The vision of this project was to develop NEMoSys such that it can be incorporated into other tools easily, used as a standalone tool with minimal training and expertise, or integrated into a public or private network as a web service. Therefore, providing an infrastructure that is both amenable to web service publication and is module-compatible with similar projects used in nuclear modeling and simulation is crucial to the success of the project. NEMoSys is being commercialized as Promesh™ to provide meshing support for geometries of interest to modeling and simulation while enabling use of modern high-fidelity methods in industry and beyond. These Illinois Rocstar innovations will better serve the needs of the modeling and sim- ulation (M&S) community in addition to increasing the areas in which Promesh™ can be applied. This commercial version of NEMoSys delivers advanced, adaptive refinement solutions for high- performance, multiphysics M&S software. By combining state-of-the-art meshing technology with an integrated, easy-to-use meshing solution, the Promesh™ package offers fully integrated, auto- mated meshing workflows for open-source and proprietary software. Services for automated mesh generation (tri, quad, full-tet, hex-dominant, and polyhedral), physics-based adaptive refinement, accurate and conservative grid-data transfer, database format conversion, quality assessment and improvement, and automated solution verification are implemented within NEMoSys and will be released in Promesh™. With multiple interfaces (CLI, C++ library, and Python API), Promesh™ offers competitive standalone and integrated solutions to complex meshing problems.
