v1.1 · June 2026
Unified workflow, data roadmap, and pile fields
The validated geo-energy demo, pile-field thermal interference, time-varying and seasonal loads, data-driven workflow, and digital-platform roadmap.
Resources
Documentation, validation, and the THMC-G platform roadmap
Everything you need to understand the Terra Multiphysics workflow: geometry, meshing, material characterization, constitutive modelling, boundary conditions, coupled solving, visualization, scientific data management, AI support, and the path to custom apps and digital twins.
Documentation
Start here
From a first solve to the full geometry-to-results workflow, the documentation walks engineers and researchers through every module.
Quick-start
Build a single energy pile from scratch, mesh it, set it up, and run your first coupled solve in minutes - no external pre-processor.
Learn more →User manual
The complete reference for the geometry builder, mesher, material setup, constitutive laws, coupled solver, data layer, AI-assisted tools, and visualization.
Learn more →Tutorials
Worked, step-by-step cases — single piles, borehole loops, and dense pile fields — that mirror the validated application gallery.
Learn more →Theory & validation
The coupled THMC-G formulation, validation evidence, analytical checks, benchmark roadmap, surrogate checking, and scientific data workflows.
Learn more →Quick-start: from install to first result
1
Install
Run the single installer on a Windows desktop — no account, no internet, and no cluster required.
2
Build the geometry
Start a model and shape the domain with primitives and boolean operations on the built-in CAD kernel, or import a solid.
3
Set materials, laws & boundaries
Pick faces to assign conditions, define heterogeneous material regions, choose constitutive laws, and set the processes the case needs.
4
Mesh
Generate an analysis-ready tetrahedral mesh at coarse, medium, or fine resolution — built in, nothing exported.
5
Solve or predict
Run the coupled THMC-G solve, or evaluate a validated surrogate when a case has enough solver evidence behind it.
6
Explore and deploy
Read plan, section, and 3-D fields, compare candidate designs, manage scientific data, and prepare the workflow for a custom app or digital twin when the use case repeats.
The full user manual, worked tutorials, and a theory & validation reference ship with the package. Request access to receive them.
Theory & validation
The physics under the hood
No disconnected spreadsheets. A purpose-built engine keeps coupled physics, data records, visualization, and AI-assisted workflows tied to the same model.
Coupled THMC-G formulation
A custom finite-element workflow resolves thermal, hydraulic, mechanical, chemical, and gas transport processes together, with heterogeneous porous media and advanced constitutive modelling in the same project state.
See the validation →Analytical and benchmark checks
Current validation includes analytical response checks, independent reference comparisons, and full-scale field observations. The roadmap extends the evidence base toward broader laboratory and international benchmark studies.
See the validation →Data-driven model support
Surrogate models, uncertainty bands, sensitivity studies, and AI-assisted interpretation can sit on top of validated finite-element runs without replacing the traceable physics model.

FAQ
Questions engineers ask first
How accurate is it, really?
Current Terra validation includes independent multiphysics reference checks, instrumented field data, and closed-form analytical solutions for the shipped geo-energy cases. The broader THMC-G roadmap adds laboratory, field, analytical, and international benchmark evidence as new physics modules are released.
Does the AI replace the physics?
No. Surrogates and AI-assisted tools sit on top of real coupled finite-element evidence. You can run the full solver whenever you need the exact field, and the data-driven layer stays traceable to the case it learned from.
Is Terra Multiphysics claiming a quantum FEM solver?
No. The core finite-element solver remains classical. Quantum-inspired ideas belong to optimization and search workflows, not to replacing the validated physics engine.
What does it run on?
A standard Windows desktop today. Terra Multiphysics is a self-contained application with its own geometry builder, mesher, solver workflow, data layer, AI demo, and visualization tools. GPU/HPC-ready batch workflows are on the scaling roadmap.
Is my project data sent anywhere?
No. Everything runs locally on your machine. The optional natural-language copilot is the only feature that can call an external service, and only if you switch it on with your own API key.
Which systems does it cover?
Geo-energy systems, energy geostructures, underground thermal energy storage, underground hydrogen storage, CO2 sequestration, deep geological repositories, underground excavations, and geotechnical infrastructure.
How do I get it, and what does it cost?
We're onboarding early-access design partners now. Tell us what you're working on and we'll share access and commercial terms that fit your team.

Run it yourself
The current trained surrogate runs entirely client-side for the geo-energy demo. Use it as a live example of the data-driven layer planned for broader THMC-G workflows.
