Fewer runs. More answers.

The engineering loop

Train once, then ask what you could not afford to ask

01
Data you already paid for
Every finished project leaves solver runs, test-bench results and measurements behind, and none of it informs the next one.
With STOCHOS
Those runs train a surrogate model on your own physics. There is no new simulation campaign to start.
02
The questions you skip
Optimization across many parameters, sensitivity and robustness studies never run, because the solve budget goes to single designs.
With STOCHOS
Predictions arrive in seconds, each carrying how far it can be trusted, so those studies become affordable.
03
Where the solver goes
High-fidelity simulation stays essential, but it is spent on every question equally, including the ones the last project already answered.
With STOCHOS
Run the full solver where the model is unsure or where you need proof. That result feeds back into training, and the loop repeats.
In three dimensions

What the model returns on a whole body

One shape, three surfaces: the field, the model's confidence, the check.

01 Prediction
A car body seen from the rear three-quarter, coloured by predicted surface pressure, red over most of the body.
Predicted pressure field. Pressure across the whole body surface, resolved node by node, not reduced to one coefficient.
Method: surrogate modeling
02 Confidence
The same car body coloured by the model's predicted standard deviation, near-uniform blue with lighter areas at the roof, A-pillar and front wheel arch.
Predicted standard deviation. The model's own uncertainty on the same surface. It rises at the roof and A-pillar and at the front wheel arch.
Method: uncertainty quantification
03 Reality
The same car body coloured by relative error against the solver run, blue overall with red hotspots at the roof, A-pillar and front wheel arch.
Relative error. The prediction checked against the solver run. The hot regions are the ones the model had already flagged.
Generated geometry

Train on the shapes you have already built and the model learns a continuous space of geometry, not a list of variants. Every point in it is a shape it can hand straight to a solver, and the ones between your training shapes are new.

01
Bracket

Main view and top view of the same shape. Each frame is a geometry the model can hand straight to a solver.

02
Impeller

Blade count, wrap and hub profile move together, so the shape stays one continuous object rather than a set of edits.

03
Mirror housing

The shell changes shape without ever leaving the set the model considers buildable.

Method: generative design

Physics in motion

Cases that move, not one frozen state

01 Seal
A seal closing. The section is compressed and bulges sideways into the gap.
02 Mixer
A stirred vessel. The blades lift the particle bed and fold it back.
03 Granular bed
Gears in loose grains. The teeth drag grains round and pile the rest ahead.
04 Sloshing
A closed tank. The free surface rides up one wall, breaks, and runs back.

Method: surrogate modeling

Try to beat STOCHOS on an engineering problem

You get a few tries to shape a plastic bottle that passes a 26 bar pressure test at the lowest weight and cost. Then STOCHOS takes the same problem, on the same score, and you see both answers side by side.

Common questions

01How can AI accelerate CFD and FEM simulations?

STOCHOS learns a surrogate model from existing solver data, then predicts results for new parameters or geometries in seconds. Fast, uncertainty-aware predictions let you explore many more variants than the solver alone could cover, and the full simulation returns only for the designs you shortlist.

02Can STOCHOS predict full fields as well as single values?

Yes. STOCHOS handles 2D and 3D fields from CFD and FEM, as well as scalars, signals, meshes, and geometries. It can predict spatially resolved outputs for new parameter combinations, so you see more than a single KPI when comparing designs. Confidence is attached to every prediction, field or scalar.

03How does STOCHOS work with Ansys?

PI Probaligence is an official Ansys Technology Partner. STOCHOS Flow reads Ansys Workbench parameters and calls the Ansys Solver nodes for selective validation, so fast surrogate prediction connects to the solver workflows engineering teams already use. New solver results feed back into training, and the surrogate improves inside the Workbench setup your team runs today.

04How much data does STOCHOS need to be useful?

Less than most machine-learning tools, and there is no fixed minimum. DIM-GP is designed for small, expensive datasets, so teams usually start from existing solver runs: tens to low hundreds, not thousands. Above roughly a thousand samples, cheaper methods start to make more sense than a Gaussian process. How many you need depends on the physics, the number of parameters, and the outputs, and quantified uncertainty shows where the model is reliable and where more runs are worth adding.
