Model understanding
Turn technical notes and project documents into an explicit conceptual model and a reviewable assumption register.
The next way to simulate Built for PFLOTRAN
Describe the simulation. The workflow does the modeling.
Start with a clear description of the task, available data, and engineering requirements—not months of learning a complex modeling process. TMG Agent builds the PFLOTRAN model, tests it, diagnoses failures, revises the inputs, and runs again until the simulation succeeds or your judgment is needed.
- Requirements first
- Agent-built model
- Automatic correction

About PFLOTRAN
Built on the open-source PFLOTRAN community.
PFLOTRAN is an open-source, massively parallel simulator for subsurface flow and reactive transport, developed by contributors from national laboratories, research institutions, and industry. It is distributed under the GNU LGPL v2.1 or later.
A closed-loop workflow
Every failed run becomes the next corrective action.
The agent reads each solver message, finds likely problems in the model input, makes controlled revisions, and runs again. Every version, diagnostic, and decision remains available for engineering review.
- 01
Understand
Read the brief, source files, engineering constraints, and intended model behavior.
- 02
Build
Prepare the domain, mesh, materials, conditions, and a checked PFLOTRAN input deck.
- 03
Run & diagnose
Execute the model, inspect solver output, and identify the inputs behind errors, stalls, or instability.
- 04
Repair & rerun
Revise the input deck and repeat the simulation automatically until it succeeds or needs engineering judgment.
- 05
Verify & report
Confirm convergence and physical consistency, then produce traceable results and an engineering report.
Agent capabilities
A complete PFLOTRAN workbench, shaped around the run.
Input preparation
Assemble grids, properties, boundary conditions, source terms, and PFLOTRAN input with structured checks.
Automatic diagnosis and repair
Interpret failed runs, pinpoint likely input problems, apply controlled corrections, and rerun PFLOTRAN without restarting the workflow by hand.
Engineering deliverables
Post-process solver output into validated plots, reusable data products, and concise technical reporting.
Engineering guardrails
Persistent enough to get the model running. Strict enough for review.
Automated correction never hides the engineering trail. The workflow records every source file, input revision, failed attempt, solver log, validation check, figure, and report version in one project history.
- Input and unit consistency checks
- Mass-balance and physical-bound verification
- Convergence and timestep diagnostics
- Reproducible run manifests
