TRUST - The CEA’s open source HPC platform
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 acronym TRUST stands for TRioU Software for Thermohydraulics. This software was originally designed for conduction, incompressible single-phase, and Low Mach Number (LMN) flows with a robust Weakly-Compressible (WC) multi-species solver.
However, a huge effort has been conducted recently, and now TRUST is able to simulate real compressible multi-phase flows.
TRUST is also being progressively ported to support GPU acceleration (NVidia/AMD).
This software is OpenSource (BSD license), available here on GitHub.
