EC2 Modelisation

What EC2 Modelisation does

EC2 Modélisation is a French private engineering consultancy founded in 1998 and headquartered in Villeurbanne (Lyon metropolitan area), specializing in advanced finite element simulation and numerical modeling for industrial clients. The firm operates across structural mechanics, fast dynamics (crash, impact, perforation), welding simulation, buckling and modal analysis, thermal analysis, fracture mechanics (XFEM), composite and porous materials, fluid-structure interaction, and additive manufacturing process simulation, with two proprietary software products (STANLAX for thin shell stability and MODelia for porous material thermal characterization) developed in collaboration with CEA Saclay and INSA Lyon. Its business combines project-based engineering consulting, Qualiopi-certified professional training (FEM, buckling, welding, fracture mechanics), and direct licensing of its proprietary software to industrial and academic clients. EC2 is ISO 9001:2015 certified, CIR/CII accredited, and serves a roster of marquee French industrial and government accounts (EDF, Safran Aircraft Engines, IRSN, ORANO, Renault, Plastic Omnium), reaching them primarily through industry events, regional cluster membership, and CIFRE-linked academic collaborations. The company underwent a founder-to-insider leadership transition in 2021, with Romain Filippi assuming the directorship from Christophe Baillis after 12 years inside the firm.

Revenue model

1. Engineering Simulation Consulting: Core revenue stream from engineering consulting engagements involving finite element simulation, structural analysis, thermal modeling, and expert assessments for industrial clients. Projects typically involve design validation, certification support, and failure diagnosis.
2. Professional Training Services: Revenue from expert training programs in numerical simulation. EC2 is a certified training organization (Qualiopi certified) offering courses on finite element methods, buckling, welding simulation, and fracture mechanics. Training is delivered both at client sites (on-site/custom) and at EC2's premises.
3. Software Licensing / Distribution: Revenue from commercializing proprietary software products: STANLAX (thin shell stability analysis) and MODELIA (porous material thermal properties). These software tools are developed internally and distributed to industrial and academic clients.

Direct peers

• Transvalor: French software and simulation services firm specializing in materials forming, heat treatment, and welding simulation using FEM. Directly comparable niche simulation software plus engineering services model, targeting similar French industrial clients in aerospace and nuclear.
• Principia: French engineering consultancy providing FEM-based structural analysis, naval architecture, and offshore simulation. Similar B2B engineering simulation services model with strong French maritime/defense and energy client base, directly comparable in services scope.
• Numeca: Belgian developer of CFD and multi-physics simulation software (Fine/Open) with engineering services. Comparable niche simulation software + consulting model, comparable size, targeting overlapping aerospace and turbomachinery clients.
• SDTools: French specialist in structural dynamics, modal analysis, and fatigue software. Closely comparable niche expertise (vibratory fatigue, modal/seismic), same French academic-research lineage, similar size and consulting-plus-software business model.

Broad incumbents

• ESI Group: French-headquartered global leader in virtual prototyping software for manufacturing and welding simulation. Same French engineering roots and overlapping welding/dynamics/CRASH simulation domain but at vastly greater scale; a relevant incumbent competitor.
• ANSYS: Global incumbent in engineering simulation software (structural, thermal, fluids, electromagnetics). EC2's STANLAX and MODELIA complement ANSYS Mechanical; the two compete for the same industrial simulation budgets even though EC2 is service-led.
• Dassault Systèmes (SIMULIA): Owner of AbaqaLicensingFEM platform widely used by EC2's industrial clients. Same French engineering DNA at global scale, and a potential acquirer/co-developer of EC2's specialty tools.

Others

• FFT (Framatome Fuel Technology): Framatome subsidiary providing engineering and simulation services to the French nuclear sector — overlapping client base (EDF, IRSN, ORANO) and similar FEM-driven qualification work, but as internal/exclusive nuclear engineering services rather than an external simulation consultancy.
• Mécanium: Partner firm of EC2 providing experimental materials characterization. Not a competitor but an adjacent peer — combined with EC2's simulation, the two form an integrated test-simulation correlation offering for material characterization.

Regional players

• CORYS: French engineering firm specialized in process simulation and operator training simulators for energy and transport. Adjacent in being French engineering simulation services; differs in focusing on dynamic process simulation rather than FEM structural analysis.
