About Ivan

Fire and thermal simulation engineer with 13 years of experience in CFD, heat transfer and fire dynamics. Specialist in FDS, Blender geometry preparation, and FireFOAM/OpenFOAM for advanced fire modelling. I help industrial clients assess fire scenarios, heat fluxes, smoke movement and thermal risks through high‑fidelity CFD.

I deliver complete studies: geometry preparation, meshing, simulation setup, transient fire modelling, radiation/heat flux analysis, and technical reporting. Strong background in radiation modelling (FireFOAM development), multiphysics CFD and industrial environments (oil & gas, automotive, aerospace, R&D).

    Ingénieur CFD – Simulation incendie, thermique & combustion
    March 2026 - Today (4 months)
    Ingénieur CFD spécialisé en simulation incendie (FDS), combustion, thermique et mécanique des fluides.
    J’accompagne les bureaux d’études, industriels et fabricants dans la modélisation de phénomènes complexes, l’analyse de scénarios critiques et l’optimisation de systèmes thermiques.

    Je réalise notamment :
    • Simulations incendie FDS (rack fire, propagation, extinction, sprinklers, pyrolyse)
    • Modélisation de combustion solide (bois, cartons, biomasse, matériaux combustibles)
    • Études thermiques (transferts, rayonnement, convection, bilans énergétiques)
    • CFD avancé (FireFOAM, OpenFOAM, turbulence, multiphysique)
    • Post‑traitement ParaView : visualisations 3D, analyses, vidéos techniques

    Dernier projet réalisé :
    → Simulation complète d’un rack fire avec propagation multi‑niveaux, pyrolyse, double réaction, interaction sprinklers, extinction et analyse des flux thermiques.
    Production d’une vidéo technique et d’un rapport d’analyse exploitables pour décisionnel ou communication interne.

    Je peux intervenir sur :
    • études incendie réglementaires ou R&D
    • optimisation de produits thermiques
    • validation de concepts par simulation
    • surcharge ponctuelle de bureaux d’études

    Objectif : fournir des résultats fiables, exploitables et visuellement clairs.
