Simulations

Simulate first.
Build once.

SynapseX is building physics world models for fusion, semiconductors, aerospace and quantum hardware: predictions that come with an uncertainty band, a reference check and a sealed record. The panels on this page are not recordings. They solve the equations in your browser.

Why world models

The physics outgrew the loop.
Design, simulate, wait, repeat.

01

Simulation is too slow to explore.

A high-fidelity run of a plasma, a process reactor or an entry flow takes hours to weeks. A design space holds thousands of candidates. Most of them are never simulated.

02

Experiments are too expensive to guess.

A shot, a wafer lot or a tunnel entry costs real money and real schedule. Trial and error stops scaling long before the design is good.

03

Results are hard to trust and harder to reuse.

A figure without units, a model without an error bar and a run nobody can reproduce all end the same way: the work is done again.

What it does

Four verbs.
One record of what happened.

Simulate

Solve the governing equations, with the method and the reference check stated next to the result.

Live today

Quantum circuits and wave packets, error-correction Monte Carlo, your own differential equations, teaching-scale sandboxes.

In development

A world model trained on solver and experimental data returns the whole field, with an uncertainty band, fast enough to interact with.

Live today

In development

Neural-operator and physics-informed surrogates for each sector.

Explore

See how every output moves across the design space, instead of sampling a handful of points and hoping.

Device-topology comparison, threshold curves across noise models, your own sweeps as short Python runs.

In development

Interactive design-space maps over the sector world models.

Optimize

Let the search propose the next design, and send only the candidates that earn it to the solver or the experiment.

Live today

Bayesian optimisation with three acquisition rules and batch proposals.

In development

Multi-objective, constrained search over world models, closed with cluster submission.

Sectors

Extreme physics,
one instrument at a time.

Each sector below opens with what we are building and ends with a panel you can run now. The panels compute real, reduced-order physics in your browser: move a dial and the answer is solved again.

01 · Fusion

Plasma that
answers back.

Fusion design lives on magnetohydrodynamics: equilibrium, stability and transport, across magnetic, inertial and magneto-inertial confinement. We are building world models that return those answers while the design is still on the screen.

In development
  • Equilibrium and stability surrogates for magnetic confinement
  • Implosion and burn surrogates for inertial confinement
  • Compression dynamics for magneto-inertial concepts
  • Heat loads on coils, walls and divertors
  • Verification against reference codes on HPC

Limits checked: q at 95 % flux above 2, normalised beta below 3.5. Raise the current and watch the design leave them.

Computed in your browser: the Solov'ev solution of the Grad–Shafranov equation with a vacuum toroidal field. Shape, beta and q are integrals of that closed form, checked against integration on a grid. Tracers follow the field lines, slowed down. Nothing here is a recording.

Running above, in your browser. Plasma equilibrium. Change the machine and read its shape, beta and safety factor from an exact solution of the Grad–Shafranov equation. A reduced-order model, not the sector world model.

02 · Semiconductors

The reactor,
before the wafer run.

Process development spends wafers to learn what a reactor does. We are building models of reactor transport and surface chemistry in space and time, so a recipe can be explored before a lot is committed.

In development
  • Reactor flow, heat and species transport in three dimensions
  • Plasma and surface chemistry for etch and deposition
  • Profile evolution at feature scale
  • Recipe search under uniformity and throughput constraints
  • Run-to-run drift models from tool data

Non-uniformity is half the spread between the fastest and slowest points, over the mean.

Computed in your browser: finite volumes on 96 radial cells, implicit in time, checked against the Bessel solution without flow and the ideal-showerhead limit. Transport and kinetics are illustrative values for a generic precursor, not a qualified process recipe.

Running above, in your browser. Film deposition. Set temperature, pressure, showerhead gap and gas flow, and read growth rate and uniformity across a 300 mm wafer. A reduced-order model, not the sector world model.

03 · Aerospace

De-risk it
before it flies.

Mission-critical hardware gets one flight. We are building aerothermal and structural models that screen a design across its whole envelope, so the expensive tests go to the cases that matter.

In development
  • Hypersonic aerothermal surrogates with chemistry
  • Thermal protection sizing along a trajectory
  • Thermal and structural response of hot structures
  • Propulsion flow paths and nozzles
  • Uncertainty maps over the flight envelope

Halve the nose radius and the peak heating rises by √2. That trade is why entry vehicles are blunt.

Wall temperature is the radiative-equilibrium value at the nose: the temperature at which the surface radiates away what it receives.

Computed in your browser from closed-form correlations: Sutton–Graves stagnation heating, Lees' laminar distribution, Billig's shock shape, exponential atmosphere. Cold wall, laminar, zero angle of attack, no shock-layer radiation. This is the first-pass estimate, not a flow solution.

Running above, in your browser. Entry heating. Set velocity, altitude and body shape, and read heat flux, wall temperature and shock stand-off from engineering correlations. A reduced-order model, not the sector world model.

04 · Quantum hardware

we already ship.

The reference is the textbook transmission of a single energy. The packet carries a spread of energies, so the simulated value settles near it, not on it.

Computed in your browser: Crank–Nicolson on 640 grid points, Δt = 0.05. The scheme is unitary, so the norm staying at 1 is a check on the solver. Nothing here is a recording.

Running above, in your browser. Quantum dynamics. Send a wave packet at a barrier and watch it split. The scheme is unitary, so the norm staying at 1 is a check on the solver. A reduced-order model, not the sector world model.

Acceptance rules

A fast answer
is not yet a right one.

A surrogate is only useful if you know when to believe it. These are the rules a sector world model has to meet before its state on this page changes from in development to live.

uncertainty bandreference checkunits and provenancesolver fallbacksealed record

An uncertainty band on every prediction

A number without an error bar is not shipped. The band widens where the training data is thin.

A check against a reference

Each model is compared with a named solver or a measurement on named cases, and the comparison is published with it.

Units and provenance on every figure

The quantity, its units and range, the source and the reduction applied are on the figure itself.

A way back to the solver

Outside the range it was trained on, the model says so and hands the case to the full solver.

A sealed record of the run

Inputs, model version and outputs are frozen into a content-hashed record that someone else can re-run.

Capability ledger

What runs today.
What we are building.

Two states and nothing else. Live today means you can run it now in SynapseX Chat. In development means it is on the build list and not available yet.

FAQ

Simulations,
answered plainly.

No. Each panel solves its equations in your browser while you watch. Move a dial and the solution is computed again. The panels pause when they scroll off screen, and show one still frame if your system asks for reduced motion.

No. The panels are reduced-order models: a closed-form plasma equilibrium, a radial transport and reaction model of a wafer, engineering correlations for entry heating, a one-dimensional Schrödinger solver and a small Bayesian search. They show how a SynapseX simulation is presented and checked. The sector world models for fusion, semiconductors and aerospace are in development.

A model trained on simulation and experimental data that predicts how a physical system evolves in space and time, fast enough to explore a design space interactively. It does not replace the solver: it tells you where the solver is worth running. SynapseX is building world models for fusion plasmas, semiconductor process reactors, aerospace hardware and quantum devices.

In SynapseX Chat today: exact circuit simulation, one-dimensional wave-packet dynamics, error-correction Monte Carlo, device-topology comparison, your own systems of differential equations, teaching-scale sandboxes, short Python runs in a remote sandbox, Bayesian optimisation and run planning for HPC. The table on this page lists every capability with its state.

Every sector model has to meet the same rules before it leaves development: a stated uncertainty on each prediction, a check against a reference solver or a measurement, units and provenance on every figure, a fallback to the full solver when the model is outside the range it was trained on, and a sealed record of the run.

Not yet. A speed-up will be published only when it has been measured on a named case against a named reference solver, with the evidence sealed. Until then this page quotes none.

The panels on this page are free and need no account. In SynapseX Chat the quantum simulators cost 0 credits. Pricing for the sector world models will be set with design partners.

Book a demo. We are choosing design partners in fusion, semiconductors and aerospace, and their cases decide what is built first.

The panels on this page compute reduced-order physics in your browser for illustration. They are not design tools and their outputs are not qualified engineering results. Capabilities marked in development are not available yet and carry no delivery date. No speed-up or accuracy figure is quoted on this page because none has been measured against a named reference.
