Code-extensible platform Built for subsurface simulation
AI-assisted TOUGH simulation workflow.
Transform geological concepts, engineering requirements, and project documents into a complete subsurface multiphase flow simulation workflow with intelligent assistance.
TMG Agent combines decades of TOUGH simulation expertise with AI technology. It accelerates model preparation, execution, diagnostics, and reporting while engineers retain control of assumptions, validation, and decisions.
- Engineering control
- Expert validation
- Private deployment
Workflow + agent architecture
From technical intent to defensible results.
TMG Agent automates repetitive work without hiding the engineering. Project documents and model files remain the primary source, and every stage can be reviewed.
- 01
Understand
Identify objectives, geology, requirements, assumptions, and missing information.
- 02
Prepare
Develop the conceptual model, mesh, properties, conditions, sources, and simulator input.
- 03
Simulate
Execute staged runs, monitor progress, and preserve a traceable record of changes.
- 04
Diagnose
Investigate convergence, timestep, phase-transition, and input-consistency problems.
- 05
Communicate
Post-process results, create figures and tables, and generate an engineering report.
One supervised process
Specialized agents coordinate through an extensible simulator layer.
Mesh Generation
Designs the domain, refines the mesh, and checks mesh quality.
Simulation
Generates input, runs simulations, monitors convergence, and recommends corrections.
Reporting
Processes outputs, produces figures, and builds engineering reports.
Supervisor Agent + simulator adaptersTOUGH Family + Other Subsurface Simulators
Expertise + deployment + code coverage
One engineering platform, designed to expand across simulation codes.
Built from decades of TOUGH, multiphase-flow, and reservoir-simulation experience for CCS, geothermal, nuclear-waste, reactive-transport, and coupled-process applications.
TOUGH3, TOUGH4, TOUGHREACT, TOUGH+HYDRATE
Code adapters expand as each integration becomes available.
Other subsurface multiphase flow simulators
The same supervised workflow can be adapted to compatible simulation platforms.
Assist engineers—do not replace them
Automation remains reviewable, traceable, and subject to expert validation.
Cloud deployment
Fast access for academic users and small projects.
The workspace currently includes three workflows:
- Automated simulation
- Diagnostics
- Code compilation
