Simulation and engineering

Simulation software development that tests the costly decision before you commit capital to it.

Our simulation software development is for engineering, operations and product leaders facing a costly decision or a performance limit. We build validated simulations and high-performance software in C++, Rust and WebAssembly.

eORB Solutions Inc provides simulation software development for engineering, operations and product leaders. We model production lines, buildings, crowds, traffic and products, so a costly decision can be tested first. Every model is validated against measured data. We also write high-performance software in C++, Rust and WebAssembly.

Major decisions made on estimates

A new line, venue or product costs more than anyone wants to get wrong. The bottleneck, the evacuation time or the failure point is usually found after it is built. And when your own software is too slow, every workaround adds cost.

What changes

The costly question answered first

Run the line, the building or the crowd in software, change one thing, and run it again.

Results checked against reality

Every model is validated against measured data, and the error is stated in writing.

Heavy tools in a browser

Compiled code runs in a browser tab at near-native speed, with nothing to install.

Faster core software

Engine modules, services and tools written in languages built for speed.

Ready for the peak

Services are load-tested above your expected peak before they go live.

What does simulation software development include?

  • Process and line simulation

    Work flowing through a factory, warehouse or hospital, with bottlenecks found before they exist.

  • Crowd and traffic simulation

    People and vehicles moving through a venue, station or district, for planning and safety.

  • Physics and product simulation

    Rigid bodies, fluids and materials, for design and testing.

  • Engineering tools

    Solvers, optimizers and analysis tools for your engineers, with the math checked and documented.

  • High-performance code

    C++ and Rust compiled to WebAssembly, and engine modules for Unreal Engine 5 and Unity.

  • Services that hold under load

    Queues, workers and APIs in Rust and Go that keep their response times at peak traffic.

How does a simulation project run?

1

Set the question

A 30-minute conversation, then the decision to inform and the accuracy it needs, written as a number.

2

First model in two weeks

A first model running on your real data, with an early result to review.

3

Validate

Checked against measured data and a simple reference version, with the error written down.

4

Deliver in stages

A tool your team runs, with documentation, in dated stages you sign off.

5

Grow

A named lead updates the model as your operation changes, with one page of numbers each month.

Built withC++, Rust and Go, WebAssembly, CUDA, Python, Unreal Engine 5, Unity and PostgreSQL.

Questions buyers ask

How accurate is a simulation?
A simulation is as accurate as your data and the model allow, and we tell you how accurate in writing. Every model is checked against measured data from your real operation and against a simple reference version. The remaining error is stated as a number, so you know how far to rely on each result.
Can heavy computation run in a browser?
Yes. Code written in C++ or Rust and compiled to WebAssembly runs in a browser tab at near-native speed. Your engineers and partners open a link instead of installing software. Where a task needs more power than a browser offers, it runs on a server and the browser shows the results.
Do you work with our existing engineering software?
Yes. We work with the file formats, APIs and plug-in systems of the tools your team already uses. Data moves between your software and the simulation without manual re-entry. We agree in writing which tools are connected, and how, before work starts.
Who owns the simulation and the code?
You do. The source code, models and documentation are in your name from the first week. The documentation is written so any qualified engineer can maintain and extend the work. If you stop working with us, you keep everything made so far.
How much does simulation software development cost?
It depends on scope. Share your website and we'll come back with a clear plan and a written estimate. Scope, dates and the measure of success are agreed in writing before work starts. If a stage isn't delivered by its written date, you don't pay for that stage.
