Welcome on the TrioCFD website
TrioCFD (previously named "Trio_U") is a programmable software for Computational Fluid Dynamics (CFD) code, based on the TRUST platform (TRio_U Software for Thermohydraulics).

It is developed in the Thermohydraulics Service and Fluid Mechanics (STMF) of the Department of Nuclear Energy at the CEA.

The qualities of the TrioCFD code are based on a multidisciplinary research team in physical modeling, numerical analysis and software architecture.

The physical models developed, the numerical methods used and the massive parallelism of the TrioCFD code allow to simulate various problems, going from local simulations of two-phase flows to simulations of turbulent flows on industrial facilities such as portions of nuclear reactors.

TrioCFD Seminar 2017

Dear all,

We are glad to welcome you at the 2nd TrioCFD seminar which will be held in room B6 at INSTN-Saclay on Tuesday the 20th of June 2017. The access map is available here: http://www-instn.cea.fr/institut/plans-d-acces/saclay.html.

Please find below the detailed program of the day.

In order to register, please send an email to Celine LEFEUVRE <Celine.LEFEUVRE@cea.fr> before the 9th of June.

We are looking forward to seeing you,
TrioCFD team
