TRUST Platform

TRUST is a High Performance Computing (HPC) thermohydraulic engine for Computational Fluid Dynamics (CFD). 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. TRUST is also being progressively ported to support GPU acceleration (NVidia/AMD).
