• PRINCIPIA conducts digital simulation studies of complex physical phenomena for major industrial groups as well as for Energy and Defense engineering.
  • Those studies cover fields such as structural mechanics, fluid mechanics and multiphysics coupling. They are conducted throughout the systems lifecycle: pre-design, design, manufacture/installation, operation and dismantling and are most often associated with the industrial sector’s regulatory frameworks: API, EUROCODE, RCC-M, ASME, CODETI, AISC, etc.
  • PRINCIPIA also conducts engineering research on monitoring systems, basic design studies, basin tests and training.


  • Certification ISO 9001 n° 82242-2010-AQ-FRA-COFRAC
  • Catégorie: ASRC member
  • Sectors of application: Aeronautics, Spacial, Defense - Energy
  • Services provided: Consulting, expertise, training - Research and development
