Next-generation simulation End-to-end workflow automation
A new generation of TOUGH simulation.
No need to learn the full modeling process first. Describe the problem and start simulating immediately.
Start from a geological concept, engineering question, or project document. TMG Agent connects model preparation, simulation, diagnostics, visualization, and reporting for TOUGH and TOUGHREACT reactive transport projects.
Domain-guided AI and decades of TOUGH expertise automate the workflow while engineers retain control of validation and decisions.
- End-to-end automation
- Engineering control
- Expert validation
End-to-end automated workflow + agent architecture
From technical intent to defensible results—in one connected process.
Describe the problem and begin. TMG Agent connects model preparation, execution, diagnostics, post-processing, and reporting while keeping every engineering stage reviewable.
- 01
Understand
Identify objectives, geology, requirements, assumptions, and missing information.
- 02
Prepare
Develop the conceptual model, mesh, properties, conditions, sources, and simulator input, including chemical species and reactive zones for TOUGHREACT.
- 03
Simulate
Execute staged runs, monitor progress, and preserve a traceable record of changes.
- 04
Diagnose
Investigate flow, transport, and chemistry 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.
TOUGH2 / TOUGH3 / TOUGH4, TOUGHREACT, TOUGH+, iTOUGH2
Multiphase flow, heat transport, geochemistry, and inverse modeling in one family. Workflow support expands as code integrations become available.
Other subsurface multiphase flow simulators
The same supervised workflow can be adapted to compatible simulation platforms, including PFLOTRAN and OPM.
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

Private deployment
Customer data stays inside customer-controlled infrastructure.

Support transparency: Availability of a specific simulator or module depends on its release status, licensing, and completed platform integration.
