01 Preparing the geometry
Pre-processing the CAD or primitives into clean, watertight computational geometry that removes noise and irrelevant detail while preserving the features that matter.
An essential element of your CAE workflow
From models to simulation, Discreetize.ai bridges the gap in your engineering workflow.
Discreetize.ai sits in the critical “translation layer” of your simulation workflow: we take rich geometry – ranging from sophisticated CAD models for semiconductors where structures are defined at the nanometer scale, to subsurface geomodels for reservoir basins where the petrophysics operate at hundreds of kilometers — and turn them into high-fidelity, simulation-ready discretizations.
We’re the step that makes complex reality computable.
We provide advanced meshing solutions that solve the two major bottlenecks in the process:
02 Discretizing the volumes
Dividing the physical domain into elements that are “born qualified” and ready for the solver — a provably-correct mesh matched to your application (Voronoi, hex, structured, unstructured) with local refinement, boundary-layer handling, and guaranteed quality.
Automated meshing for the world’s hardest simulations
Meshing is the bottleneck.
Meshing is the bottleneck.
We remove it.
Meshing — turning a raw 3D model into the grid a solver can actually run — takes weeks of fragile, manual, expert work on every model. Discreetize collapses it into one automated, provably-correct step — and unlocks uncertainty quantification at scale.

When billions ride on a forecast, the mesh beneath it decides the answer.
Simulation drives the highest-value engineering and subsurface decisions. The mesh is where geometry meets the solver — and where the error is set, before a single timestep runs.

$85 / t Time-to-Permit and Time-to-First-Injection
Delineate the AoR faster, re-run quickly each time the regulator requests a revised model, and compress the lag from each geomodel update to a decision-quality simulation.
$10–50M+ NPV swing on a single program
From well-spacing and completion calls on one ~100-well unconventional program.
>50% Value a single mis-placed well can destroy
Through frac-driven interference between child wells.
A high-quality mesh quietly changes the result — not just its precision.
Simulation got fast.
Preparing the mesh didn’t.
Meshing is the single largest bottleneck in engineering simulation — weeks to months of fragile, manual expert work, with dedicated teams just to keep grids alive.

Born qualified: valid from the first cell — not repaired after.
Instead of building an ugly mesh and fixing it, Discreetize generates a mesh that’s guaranteed valid from the start — the first provably-correct conforming Voronoi method for non-convex, non-manifold domains.
- 01
Sample
Maximal Poisson-disk sampling places well-spaced seeds across the whole domain.
- 02
Construct
A true conforming Voronoi mesh is built directly from those seeds — without clipping.
- 03
Guarantee
Quality and geometry are captured by construction, and sharp features are preserved.
Born-qualified meshing collapses weeks of mesh prep into one run.
Compress engineering cycles
Collapse weeks of fragile, manual meshing into an automated pipeline, so simulation starts in a fraction of the time.
Quality by construction
Every mesh is born qualified — valid and conforming by construction — so you stop chasing slivers and failed runs.
Uncertainty quantification at scale
A fresh, valid mesh every run turns UQ from impractical into routine, so you can explore far more scenarios with confidence.
Mesh the un-meshable
Overlapping boundary layers, fractures, dirty CAD and complex 3D geometry — reconstructed and meshed automatically.
Why other solutions cannot produce the same results.
Today’s tools
Grid-based meshers · conventional CFD tools
- Deterministic — one fixed grid per geometry, so UQ studies are impractical
- Heuristic “ugly mesh, then fix” pipelines that are slow and human-dependent
- Struggle with overlapping boundary layers, fractures and complex 3D geometry
- Rising compute overhead and lead time as geometry complexity grows
The Discreetize edge
Structurally different
Quality by construction
Validity is guaranteed, not patched — no sliver chasing, fewer failed runs.
Sampling unlocks UQ
A fresh, valid mesh every run turns mesh error into a sampled variable, so you can explore far more scenarios.
Know-how, not just code
Open-sourced legacy code is useless without the intelligence to apply it correctly.
Live today for oil & gas.
AutoMesh-Geo starts where the geometry is hardest — the faulted, layered subsurface, from reservoirs to CO₂ storage. More verticals are on the way.
Oil & Gas
Faulted, layered reservoirs and CO₂ storage — conforming Voronoi (PEBI) grids that honor every fault and horizon.
