TRUST is a High Performance Computing (HPC) thermohydraulic engine for Computational Fluid Dynamics (CFD) developed at the Departement of System and Structure Modelisation (DM2S) of the French Atomic Energy Commission (CEA).

The software was originally designed for conduction, incompressible single-phase, and Low Mach Number (LMN) flows with a robust Weakly-Compressible (WC) multi-species solver. A huge effort has been conducted recently, and now TRUST is able to simulate real compressible multi-phase flows.

TRUST is also progressively ported to support GPU acceleration, using the Kokkos library. It has been selected to be a demonstrator of the CExA project.

TRUST serves as the kernel of several CEA application codes. The TrioCFD software is an open source example. This software is OpenSource (BSD license), available here on GitHub.
