The platform

One application, from geometry to digital twin

Build the geometry, mesh it, characterize heterogeneous materials, configure constitutive laws and boundary conditions, solve coupled THMC-G physics, and interpret the results inside one object-oriented desktop workflow. The same model becomes the base for scientific data management, custom simulation apps, digital twins, uncertainty studies, and AI-assisted decision support.

Object model

Engineering intent stays attached

Solids, faces, pipes, materials, constitutive laws, boundary conditions, physics settings, solver cases, scientific data, and result fields live as named objects inside the same project.

Boundary conditions belong to faces

Pick a face once. Its thermal or mechanical condition follows that face through meshing and solver handoff.

Materials and laws stay reusable

Soil, rock, gas, fluid, and pipe definitions are model objects, so heterogeneous regions can reuse the same constitutive laws without duplicating input blocks.

Runs and data stay traceable

Each solver case carries its settings, source objects, mesh, monitoring records, and result fields. You can compare runs without losing where they came from.

Module 01

Geometry builder

Build the model from scratch on an owned CAD kernel - no external pre-processor in the loop.

Primitives and booleans

Start from boxes, cylinders, and other primitives, then combine them with boolean union, cut, and intersection, plus transforms, to build the model geometry directly in the app.

Face-level boundary conditions

Pick individual faces of a solid and assign temperatures or other boundary conditions to them, so the boundary setup follows the geometry instead of a separate mesh-side workflow.

Save, load, reuse

Save a model and reopen it later. The geometry flows straight into meshing, THMC-G solving, visualization, data management, and deployment as one reproducible pipeline.

Module 02

Mesher

A built-in mesher turns the geometry into an analysis-ready tetrahedral mesh, automatically.

Automatic tetrahedral meshing

Mesh the model directly from the built geometry — no hand-built elements and no external pre-processor between geometry and solve.

Coarse, medium, or fine

Choose a resolution to trade speed against detail. A design mesh resolves the trends quickly; a fine mesh sharpens the field where it matters.

Straight into the solver

The mesh hands off to the coupled engine as part of one reproducible pipeline, so geometry, mesh, solve, visualization, data records, and deployment studies stay self-consistent.

Module 03

THMC-G solver

A custom finite-element solver resolves coupled thermal, hydraulic, mechanical, chemical, and gas transport processes together, with support for heterogeneous and evolving porous media.

Monolithic coupling

A monolithic Newton-Raphson scheme solves the coupled fields together, capturing feedback between heat, flow, deformation, chemical change, and gas transport.

Advanced constitutive modelling

Soil and rock constitutive laws, transport parameters, and heterogeneous material regions are explicit model objects, ready for laboratory calibration and field comparison.

Subsurface system coupling

Engineered components, porous media, and boundary processes are resolved inside the same solve, so the platform can grow from geo-energy cases to broader subsurface infrastructure.

A real energy-pile in-situ test, Faizal et al. 2016: the measured ground response against Terra’s finite-element field — daily-average outlet MAE 0.04–0.08 °C after one global outlet calibration.
Module 04

Data-driven workflows and AI support

Validated coupled runs, monitoring data, uncertainty quantification, and surrogate models can turn the finite-element platform into fast design exploration and AI-assisted decision support.

Fast design feedback

For the current geo-energy demo, outlet temperature, heat delivered, and pressure drop return in one shot - validated to R² 0.9997 against held-out solver runs.

Uncertainty and sensitivity

Global sensitivity, confidence intervals, and uncertainty bands show which inputs drive the result and where the model needs better data.

AI-assisted decision support

Map candidate designs to a performance frontier, connect field observations to model updates, and use AI support to help interpret scenarios without losing traceability.

Sweep the key inputs and watch the predicted performance move in real time — the surrogate evaluates candidate designs as fast as you can drag a slider.
Module 05

Scientific visualization

Read the result without exporting it. Integrated plan, section, and 3-D views render fields straight from the same finite-element model.

Plan, section, and 3-D fields

Inspect the model as plan views, vertical sections, or colour-mapped 3-D fields, with result interpretation tied back to the source objects.

One finite-element model

See domain, engineered components, and subsurface fields together - self-consistent IDs straight from the same solve, no re-import.

Orbit and inspect

Rotate the result to look at the field from any angle - interactive 3-D results in the same workflow as geometry, mesh, solve, and data review.

Deployment roadmap

From design tool to digital platform

The current product is a desktop workflow for validated subsurface modelling. The next layer packages those workflows into repeatable tools teams can deploy, automate, connect to field systems, and use as operating digital twins.

Custom simulation apps

Package a validated Terra Multiphysics workflow for one repeated engineering task, so teams can run it without rebuilding the model from scratch each time.

Operating digital twins

Connect design models to monitored field data, compare expected and observed behaviour, and help owners tune subsurface assets over time.

Imaging, UQ, and GPU/HPC workflows

Scale batch solves, geophysical imaging links, uncertainty studies, surrogate training, and larger validation campaigns while keeping the desktop app as the engineering control room.

Requirements

Runs on your desktop today

A standard Windows desktop is enough for the current application. Terra Multiphysics is self-contained - its own geometry builder, mesher, solver workflow, visualization, data layer, and AI demo, with GPU/HPC scaling on the roadmap.

No cloud required

The current workflow runs locally on your machine. No cloud account or internet connection is required to model, mesh, solve, manage project data, or view results.

Your data stays put

Project data never leaves your computer. 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.

One self-contained app

Geometry, meshing, material setup, the coupled solver, visualization, and data-driven tools ship as one installer - no external pre-processor and no dependency chase.
