MOOSEnger's Core AI-Driven Workflow
MOOSEnger converts natural-language simulation requests into runnable MOOSE input files by combining Retrieval Augmented Generation (RAG) with MOOSE-aware tools. This workflow includes parsing, validation, and execution, addressing the common challenges in authoring MOOSE simulations.
Robust Input Precheck Process
MOOSEnger implements a deterministic input-precheck pipeline to ensure high reliability before simulation execution. This multi-stage process proactively identifies and corrects common input errors.

Execution Pass Rate Comparison
MOOSEnger dramatically improves the success rate of generating executable MOOSE input files compared to an LLM-only baseline, particularly for complex multiphysics problems.
| Problem Family | MOOSEnger (Pass) | LLM-only Baseline (Pass) |
|---|---|---|
| Diffusion | 25/25 (100%) | 9/25 (36%) |
| Transient heat conduction | 23/25 (92%) | 0/25 (0%) |
| Solid mechanics | 24/25 (96%) | 0/25 (0%) |
| Porous flow | 23/25 (92%) | 1/25 (4%) |
| Navier-Stokes | 21/25 (84%) | 0/25 (0%) |
| Overall | 116/125 (93%) | 10/125 (8%) |

Execution Pass Rate with MOOSE Runtime In-Loop
By placing the MOOSE runtime 'in the loop' for smoke tests and iterative correction, MOOSEnger significantly raises the execution pass rate. This contrasts with an LLM-only baseline (0.08), demonstrating the power of integrating domain-specific tools for 'verify-and-correct' updates.
Scalable and Extensible AI Architecture
MOOSEnger adopts a core-plus-domain architecture that separates reusable agent infrastructure (configuration, registries, tool dispatch, retrieval services, persistence, and evaluation) from MOOSE-specific capabilities (HIT-based parsing, syntax-preserving ingestion, and domain-specific utilities for input repair and checking). This design promotes rapid development of new MOOSE-based application agents and multi-agent workflows for complex reactor multiphysics, ensuring adaptability and modularity across the MOOSE ecosystem.

Your Path to AI-Powered Simulation
A phased approach ensures seamless integration and maximum impact for MOOSEnger within your existing infrastructure and workflows.
Phase 1: Discovery & Integration (2-4 Weeks)
Assess current simulation workflows, identify key integration points for MOOSEnger, and establish initial knowledge base ingestion. Define success metrics and a pilot project.
Phase 2: Pilot Deployment & Customization (4-8 Weeks)
Deploy MOOSEnger in a sandboxed environment with a select group of users. Customize prompt packs, domain-specific tools, and refine RAG sources based on initial feedback. Begin iterative 'verify-and-correct' loops.
Phase 3: Scaled Rollout & Continuous Improvement (8-12 Weeks)
Expand MOOSEnger access across relevant engineering teams. Implement ongoing evaluation frameworks, gather structured diagnostics, and continuously update the knowledge base and agent skills based on usage patterns and performance data.
