TRUST is an open-source HPC-based thermal-hydraulic CFD simulation platform developed at CEA (Department of Energy). It is designed for the solution of single-phase incompressible Navier-Stokes equations. An increasing effort is being made to allow the resolution of multi-phase compressible flows. TRUST has a very good scalability allowing simulations of more than 2 billion elements on 50 000 processors. TRUST is used as the basis for many specialised applications in the nuclear and new energy fields.
