Aether Simulation.

One model that forward-rolls every physics.

Simulation is the act Aether was trained for: it rolls a physical system forward in time — CFD, FEA, electromagnetics, thermal, acoustics, quantum chemistry and molecular dynamics — coupled on one mesh, validated against measured reality, from a real-time surrogate to first-principles DNS. Ten physics domains under one model, with the uncertainty on every result and the setup automated.

Every physics, under one model.

The incumbent CAE stack is a dozen seat-licensed solvers that each speak one physics and a different file format. Aether Simulation is one model and one mesh — built so the flow that loads a structure and the heat that warps it are solved together, not imported between two tools with a fudge factor in the middle.

01

Computational fluid dynamics

Incompressible and compressible flow, turbulence, multiphase and reacting flow — steady and transient, validated against wind-tunnel and rig data.

02

Structural & FEA

Linear and nonlinear statics, dynamics, contact, plasticity and fatigue — the load path resolved, not approximated.

03

Electromagnetics

Full-wave, quasi-static and high-frequency EM for antennas, signal integrity, motors and EMC.

04

Thermal & heat transfer

Conduction, convection and radiation, steady and transient — coupled to flow and structure where they meet.

05

Multiphysics coupling

Fluid-structure, electro-thermal, thermo-mechanical and beyond — solved together on one mesh, where single-physics tools silently drop the interaction that matters.

06

Acoustics & vibration

Modal, harmonic and aeroacoustic analysis for NVH, sound radiation and resonance.

07

Quantum chemistry / DFT

First-principles electronic structure for energies, forces and properties across the periodic table.

08

Molecular dynamics

Classical and ML-interatomic-potential MD for materials, fluids and soft matter at scale.

09

Mesh & geometry

Automatic meshing, defeaturing and adaptive refinement from CAD — the setup that usually eats the schedule, automated.

10

Solver autoconfiguration

Natural language to a configured case: solver, boundary conditions, time-step and convergence chosen and justified.

11

UQ & validation

Calibrated uncertainty on every result, with residuals reported against measured data — a number you can sign off, or an honest “not yet”.

12

Optimization & inverse

Latin-hypercube DOE, sensitivity, multi-objective optimization and inverse design driven by the same solver that validates the answer.

The integrity contract

Every solve knows how good it is.

A surrogate is never presented as high-fidelity, and a simulation is never presented as measurement. The four-tier ladder makes the fidelity explicit, and every result carries its calibrated uncertainty.

T1

Reduced-order surrogate

Distilled, real-time models for screening, control and many-query design — milliseconds, always labelled with their accuracy bound.

T2

Real-time simulation

Interactive multiphysics at the fidelity most engineering iteration lives in — fast enough to sit in the loop.

T3

High-fidelity

Full-resolution coupled solves validated against measured data — the tier behind a decision you have to be right about.

T4

First-principles / DNS (escalation)

Direct numerical simulation, DFT and detailed multiphysics. A regime the model cannot yet resolve returns the engine it requires — never a fabricated field.

Where it's used

Six engineering worlds, one solver.

Not a tool per domain — one model whose physics changes per problem but whose contract does not.

Aerospace & automotive

External aero, crash, NVH, thermal and coupled FSI — the cases that used to need three solvers and an import in between.

Electronics & silicon

Electro-thermal, signal integrity and EMC on the same model that runs the chip flow.

Energy & process

Combustion, multiphase flow, heat exchangers and structural integrity for power and process plant.

Materials & chemistry

DFT and MD for properties, reactions and transport, closing the loop with the materials discipline.

Acoustics & NVH

Sound radiation, cabin noise and resonance, coupled to the flow and structure that drive them.

Biomedical

Hemodynamics, soft-tissue mechanics and device interaction with deformables.

Platform

Coupled, and measured.

The difference between a simulation that ships and one that demos is whether it's coupled and validated. We report what was solved and what was measured.

Vs the CAE stack

Every solver, one model.

The incumbents each own a physics and a file format, coupled across tools with a fudge factor in the middle. Aether solves them together on one mesh, with calibrated uncertainty.

Why the cycle shortens

Engineering cycles, compressed.

What compounds is solves per quarter, not any single run being faster.

CFD, FEA, EM, thermal, acoustics, quantum chemistry, MD and their couplings — one model instead of a shelf of seat-licensed solvers.

Fidelity ladder
4-tier

Surrogate → real-time → high-fidelity → first-principles. Every solve carries its tier, provenance and calibrated uncertainty.

Against reality
Measured

Validated against wind-tunnel, rig and field data — the difference between a simulation you trust and a pretty contour plot.

AI scientists, not chatbots

An AI that runs the analysis, not a solver seat.

It reads the problem, sets it up, picks fidelity, validates against data, and writes the rationale — for an expert audience.

  • 01

    Reads the problem

    Ingests the geometry, the loads and the question, and decomposes it into a typed study — physics, couplings and acceptance criteria — before any solve runs.

  • 02

    Sets it up

    Meshes, picks the solver, boundary conditions and time-step, and justifies each choice — the setup that usually eats the schedule.

  • 03

    Picks the right tier

    Knows when a real-time surrogate suffices and when a decision needs high-fidelity or DNS — by the confidence the conclusion requires.

  • 04

    Validates against data

    Reports residuals against measured reality and calibrated uncertainty; out-of-domain inputs are flagged, not silently extrapolated.

  • 05

    Writes the rationale

    Each result ships with its fidelity tier, the assumptions, the margins and the model-version hash — an engineer can sign it off.

  • 06

    Closes the loop

    Measured outcomes return into the model, so the simulation that designed a part gets better at predicting the next one.

Where this leads

Simulation that gets truer with every test.

Each measured result returns into the model, so the solver that designed a part this quarter predicts it better the next — and the gap between simulation and the rig closes.

FAQ

Good to know.

How does this compare to commercial CAE suites, commercial CAE suites, multiphysics suites or open-source CFD?

Those are single-physics or loosely-coupled solvers with per-domain seat licences and inter-tool imports. Aether forward-rolls every physics on one model and one mesh, validated against measured reality, from real-time surrogate to first-principles.

Is it accurate enough to sign off?

High-fidelity solves are validated against wind-tunnel, rig and field data with calibrated uncertainty and reported residuals. When the model can't resolve a regime, it says so and names the engine required — it never fabricates a field.

Can it really couple physics?

Yes — fluid-structure, electro-thermal, thermo-mechanical and more solve together on one mesh, so the cross-domain interaction that drives real failures isn't dropped.

Can I run it air-gapped?

Yes — like the rest of Aether it deploys managed, in your VPC, on-prem or fully air-gapped, on Aether Cloud's compute.

Run the physics on one model.

Aether forward-rolls every physics — coupled, validated and uncertainty-quantified — from a real-time surrogate to first-principles. Request access to deploy it behind your firewall, or see the engineering discipline it powers.

Simulation is the act under every discipline — one model, every physics.
