Release V1.9.1
TRUST is a thermohydraulic software package for CFD simulations. It was originally designed for incompressible single-phase and Low Mach Number flows, but now also allows simulating real compressible multi-phase flows.
TRUST is also being progressively ported to support GPU acceleration (NVidia/AMD).
This software is OpenSource (BSD license).
Please note that the syntax has evolved for some keywords, but the old syntax will be supported until v1.9.3. For more details, please refer to the release notes.
New TRUST version released v1.9.1

23/11/21 (TRUST) Convergence : Use the true residual (instead of preconditioned one) for convergence test with PETSc solvers used on non-symmetric linear system (may be necessary to lower seuil option to have same results than 1.8.3)
23/11/21 (TRUST) Keyword : Add pression option to Navier Stokes initial conditions to initialize velocity and pressure field
15/11/21 (TRUST) Fix : Several problems solving different physics on a same domain produced corrupted lml/lata/med files (mesh repeated) during post-processing
29/10/21 (TRUST) Keyword : Syntax change for Champ_Fonc_tabule. The new syntax is Champ_fonc_tabule { pb field } nbcomp { table } (the old syntax was Champ_fonc_tabule field nbcomp { table } )
29/10/21 (TRUST) Keyword : Syntax change for Champ_Fonc_Fonction, Champ_Fonc_Fonction_txyz, and Sutherland where the problem name should be passed before that of the field
29/10/21 (TRUST) Major Change: Tables defined with a Champ_fonc_tabule should be strictly monotonic (declaring a multiple times and/or a decreasing time order will stop the code execution)
29/10/21 (TRUST) Major Change: Champ_fonc_tabule supports arbitrary number of parameter fields from variables instanced in any problem
21/10/21 (TRUST) Library : Add of the vectorization library Vc (1.4.2)

18/10/21 (TRUST) Major Change: Media with variable densities do not inherit anymore from "Fluide_Incompressible"
18/10/21 (TRUST) New feature : New medium "Fluide_Dilatable_base" from which the Quasi-Compressible and the Weakly-Compressible media inherit
18/10/21 (TRUST) New feature : New problems "Pb_Thermohydraulique_WC", "Pb_Thermohydraulique_Especes_WC" and "Pb_Hydraulique_Melange_Binaire_WC" introduced to solve thermo-hydraulic and/or binary/multi species flows using a Weakly Compressible formulation (non-uniform pressure in the state equation)
16/09/21 (TRUST) New feature : Solveur_U_P is now unified for Poly/Covi-MAC discretizations and allows the monolithic resolution of the NS equation
16/09/21 (TRUST) New feature : Decouper_multi allows to partition multiple domains while accounting for connections via Raccords (allows for easier implementation of thermique_monolithique in parallel)
16/09/21 (TRUST) Major Change: All DoubleTabs associated with fields (Champ_Inc, Champ_Don, ...) have now dimension >= 2
16/09/21 (TRUST) New feature : Add interface_bloc which is a generalization of the "contribuer_a_avec" and "ajouter" API for equation, Operateur, Source to fill the jacobian matrix and the right hand side of a coupled system of equation
16/09/21 (TRUST) New feature : New "SETS" and "ICE" solveur for Schema_Euler_Implicite. Can be used with Pb_Multiphase to solve the coupled system of equations using a newton method and a pressure reduction of the linear system. ICE must respect CFL condition, SETS adds prediction steps to increase numerical stability, allowing to perform CFL>1
16/09/21 (TRUST) New feature : New medium "Milieu_Composite" to aggregate differents Fluide_base media. Can be used within a Pb_multiphase
16/09/21 (TRUST) New feature : New medium "Fluide_reel_base" to define pressure and temperature dependant laws
16/09/21 (TRUST) New Feature : A new discretization "CoviMAC" (Numerical schema on polyedrons, main difference with PolyMAC : no more auxiliary variables for scalar unknowns) is now available and can be used with Pb_Multiphase. Implemented with the new Interface_bloc API
16/09/21 (TRUST) New feature : New problem "Pb_multiphase" with 3 equations (mass, momentum and energy conservation), having each N components. N=1 corresponds to a single phase model, N=2 corresponds to a 2 fluid model, and N>2 to a multi-field model
19/08/21 (TRUST) Portability : ARM partition of Irene Joliot cluster supported
19/08/21 (TRUST) Performance : Arrays obtained from octree algorithm are cached. Useful for advanced fields computation needing interpolations each time-step
19/08/21 (TRUST) Bug fixed : Regression since 1.8.3 fixed (malformed .dt_ev file with missing columns for coupled problems)
19/08/21 (TRUST) Performance : Output files (.out) are opened/closed at the first/last print and not at each print as before
19/08/21 (TRUST) Bug fix : Source_generique source term couldn't be used for PolyMAC discretization
12/07/21 (TRUST) Performance : A same advanced field used by several probes are now computed only once during each post-processing phasis
05/07/21 (TRUST) Portability : New CCRT cluster topaze supported (110592 AMD Milan Epyc cores)
