Numersalis Engineering

Engineering and software development services

Numersalis Engineering carries out your simulation studies, CAD designs and development projects with the same rigour as our training. Two ways of working: outsourced to our office, or a consultant on assignment at your site.

What we do

From a one-off study to a project lasting several months, we work across four families of technical services and three families of software development. Every assignment starts with a written scope (deliverables, milestones) and ends with a documented handover.

Developer Tools & Automation

Automate repetitive tasks to free up your teams' time.

CAD Design & Modelling

From sketch to manufacturing: reliable models ready for industrialisation.

CFD & Fluid Process Simulation

Reliable analyses and quality deliverables to inform your technical decisions.

IT Services

Versatile expertise for your digital environment.

PMO & Project Management

More visibility, deadlines and costs under control, from kick-off to delivery.

Mobile App Development

From idea to the stores: an app we have already built for ourselves.

Custom Software Development

Software that fits your processes, not the other way round.

Website Development

A fast, well-indexed site that is easy to keep alive.

Two ways of working together

Outsourcing: hand us the subject

You send us a specification; we carry out the study or the development in our office in Palaiseau, with our tools, and deliver results, models and a report. Ideal to absorb a peak of work or to cover a subject outside your in-house skills.

Consultant on assignment: reinforce your team

A Numersalis engineer joins your team, on site or remotely, for a defined period. They work with your tools and processes, under your direction, and pass their methods on to your staff. Ideal for a long project or a rare skill (1D simulation, CFD, Power BI…).

How we work

Scoping: a technical conversation to understand the need, the constraints and the available data, followed by a priced proposal.
Delivery: regular progress reviews; assumptions and intermediate results reviewed with your teams.
Handover: models, source code, reports and summary presentations; everything produced belongs to you.
Transfer: training your teams to take over the deliverables, then support after delivery.

Frequently asked questions

Both. We work from a few days for a one-off need (checking a sizing, producing drawings, automating a report) to several months for a large project (a full CFD study, a mobile app).

Simulation: Simcenter FloMaster, Simcenter STAR-CCM+, ANSYS Fluent, Autodesk CFD. CAD: SolidWorks, CATIA, Creo, AutoCAD. Development: Python, VBA, HTML/CSS/JavaScript, modern web and mobile frameworks. We can also work on your licences.

Yes. Our consultants work across France, and many assignments run remotely with regular video calls. For clients abroad, we work in English, remotely.

You do. Models, source code, reports and documentation are transferred on delivery, unless the quote states otherwise.
