What is RTECH (rtech.fr)?

Updated

RTECH (rtech.fr) is a French SME specializing in advanced numerical simulation and scientific software development, with over 25 years of expertise in the aerospace sector. Founded in 2000, it works alongside major aerospace organizations, research institutions, and technology companies. If you need to understand what the company does, who it serves, and where its expertise lies, this overview covers the essentials.

What RTECH does

RTECH turns complex physical phenomena into usable data that supports technical and strategic decisions. Its work spans three main activity areas:

  • Numerical simulations — Predicting complex physical behavior to support design decisions and reduce risk.
  • Scientific software development — Building robust, tailor-made software for advanced scientific applications.
  • Software distribution — Delivering specialized scientific tools to the organizations and researchers who need them, including GridPro, an advanced mesh generation tool.

Core areas of expertise

RTECH's technical strengths center on multiphysics mechanics and related disciplines:

Domain Examples
Multiphysics mechanics Fluid mechanics, thermal analysis, thermochemistry, radiation, materials
Coupled physics Thermal coupling, aerothermodynamics
Specialized topics Plasma, space debris, fragmentation
Software & data Big data, machine learning, flight physics, simulators

The company describes its mission as "modelling reality to understand it better… and predict it better" — transforming phenomena such as compressible flows, heat transfers, plasma-material interactions, and fragmentation into data that guides engineering and strategic choices.

Who it works with

RTECH collaborates with leading organizations in aerospace, research, and technology. Its track record, as stated on its site, includes:
