--------------------------------------------------------------------------------------------------
Release notes version 1.9.5 : Enhancements, modifications and corrected bugs since version 1.9.4 :
--------------------------------------------------------------------------------------------------
20/11/24 (TRUST) Tools : 'trustpy' now becomes 'trustify'. Check the syntax of your dataset with 'trust -trustify my_case.data'. See a more complete usage example in Outils/trustify/doc/examples/hello_world.
28/10/24 (TRUST) New feature : Support for Cathare FORT21 format in lata tools and plugins.
28/10/24 (TRUST) Build : TRUST is now configured by default with Kokkos SIMD (if C++17) backend enabled
21/10/24 (TRUST) Bug fix : In VEF, Viscous forces on boundaries (printed in *_Contrainte_visqueuse*.out files) in incompressible Navier-Stokes equations were computed as Integral(-mu*grad(u)*ndS). It is now computed as Integral(-mu*(grad(u) +grad(u)^T)*ndS).
18/10/24 (TRUST) Minor change : To force C++14 build of TRUST, you should add configure option -std=c++14. Else by default, it will use C++17 as TRUST features from Kokkos (GPU, SIMD, OpenMP) are not available with C++14
18/10/24 (TRUST) Fix : .out files were not closed at the end of the calculation leaving opened file descriptors
17/10/24 (TRUST) GPU : Upgrade AmgX multigrid solvers with a better performance (10-15%) noticed on benchmarks
17/10/24 (TRUST) GPU : When enabling GPU communications with MPI GPU-aware library, fix KSP_DIVERGED produced by PETSc GPU solvers (especially when using classical multigrid preconditioners) by using OpenMPI 5.x instead of OpenMPI 4.x
07/10/24 (TRUST) New Keyword : Added a new correlation for Nusselt heat flux, including Nusselt parser with Reynolds (Re) and Prandtl (Pr) number dependency.
07/10/24 (TRUST) New Feature : Move correlation structures from Pb_Multiphase to Probleme_base (allow to use CMFD type turbulence or parietal heat transfer correlations with (thermo)hydraulic problems for example). TrioCFD needed for turbulence equations.
07/10/24 (TRUST) Tools : Patched MEDCoupling to add crackAlong() functionality.
26/09/24 (TRUST) Change : cmake upgraded from 3.22 to 3.30.
26/09/24 (TRUST) Change : python upgraded from 3.7 to 3.12.
26/09/24 (TRUST) Change : mpi4py upgraded from 3.0.3 to 4.0.0.
03/09/24 (TRUST) GPU : A1000, A2000, H100 GPUs and Cuda 12.x supported. Add ./configure -kokkos_hip option to build on AMD with HIP Kokkos backend (still buggy) so default is still OpenMP-target backend (with performance issue on MI250)
03/09/24 (TRUST) GPU : VEF convection schemes muscl_new and EF_stab available
03/09/24 (TRUST) GPU : Complete porting for VEF dicretization of Quasi-compressible module and wall laws for turbulence models. Optimization with a lot H2D&D2H copies suppressed
25/07/24 (TRUST) Bug fix : Performance regression fixed in IJK (seen in FT application in TrioCFD)
18/07/24 (TRUST) Fix : Possible to visualize surface fields issued from Champ_post_extraction with VisIt
12/07/24 (TRUST) GPU : Enable HIP support in PETSc to get Hypre multigrid available on AMD GPU with: petsc_gpu gcp|gmres { precond boomeramg { } ... }
12/07/24 (TRUST) GPU : New available features for VEF discretization: Quasi-compressible (partial), Wale and Smagorinski turbulence models, Semi-implicit scheme, Sources term (Boussinesq, Canal_perio)
09/07/24 (TRUST) New feature : Add new problem/equation Pb_Multiphase_Enthalpie/Energie_Multiphase_Enthalpie : resolution in h not in T
--------------------------------------------------------------------------------------------------
Release notes version 1.9.4 : Enhancements, modifications and corrected bugs since version 1.9.3 :
--------------------------------------------------------------------------------------------------
17/05/24 (TRUST) Minor change : In Jupyter validation form Python API, method 'run.description()' is not available anymore. A MarkDown block should be used instead
17/05/24 (TRUST) Keyword : Champ_front_parametrique (boundary fields list) and Champ_parametrique (fields list) to chain multi-stationary or stationary-transient scenarios (see V&V sheets under Verification/Champs). Experimental, only tested with Flica5
16/05/24 (TRUST) Tools : Upgrade to MEDCoupling 9.13.0
13/05/24 (TRUST) New feature : New LES Smago/WALE models developped for Pb_Multiphase. To be used in TrioCFD (CMFD module !)
06/05/24 (TRUST) New feature : Performance logs (TU files): XX_comm.TU and XX_detail.TU have been replaced by XX_csv.TU which contains a CSV formated logs of the computation times. Keyword 'stat_per_proc_perf_log' can be used to obtain detailed performance logs per processor. See validation form 'HowTo/Post_treatment_performance' for detailed explanation on how global TU information are computed.
30/04/24 (TRUST) New Keywords : 'Fields_file', 'Statistics_file', 'Serial_statistics_file', 'Mobile_Probes_file', 'Int_Probes_file' and 'Int_Arrays_file'
can now be used to define post-processing blocs in an annex datafile. See 'postpro_annex_file' test case
12/04/24 (TRUST) Keyword : .xyz file may be written in ASCII format with "EcritureLectureSpecial EcrFicPartage" keyword. Fields are written in "x(i) y(i) z(i) value(i)" format
10/04/24 (TRUST) Fix : Element-wall distance is now correctly calculated in the diffusion-operator for multi-component cases
10/04/24 (TRUST) New feature : Add series of problems XXX_List_Concenration & XXX_List_Concenration_Turbulent that can be used to dolve a list of N concentration equations. Possible to define different diffusion coefficients for each cloned equation (which is not the case of list_scalaire_passif problem !!!)
10/04/24 (TRUST) New feature : Add series of problems XXX_Cloned_Concenration & XXX_Cloned_Concenration_Turbulent that can be used to state only a single concentration equation in the .data but clone N equations. We assume here that the same BC are used. Possible to define different diffusion coefficients for each cloned equation.
08/04/24 (TRUST) Keyword : Keyword 'ecrire_fichier_xyz_valeur' is now used in a single block, with attributes 'dt', 'fields' and 'boundaries'
20/03/24 (TRUST) New feature : CoolProp and EOS can now be used with Dilatable flows problems
07/03/24 (TRUST) New feature : New syntax available for facsec with Euler implicit scheme, more options allowed in datafile to monitor facsec behavior: facsec { [facsec_ini] [facsec_max] [rapport_residus] [nb_ite_sans_accel_max] }. It can also be a function of time, as follows: facsec expression(t)
07/03/24 (TRUST) Keyword : Obsolete syntax for Champ_Fonc_Fonction, Champ_Fonc_Fonction_txyz, and Sutherland (pre v1.8.4) is not accepted anymore.
07/03/24 (TRUST) Keyword : Obsolete syntax for Champ_Fonc_tabule (pre v1.8.4) is not accepted anymore. Syntax should be on the form Champ_fonc_tabule { pb field } nbcomp { table }
07/03/24 (TRUST) Change : EcritureLectureSpecial is forced to 0 for PolyMAC_P0 simulations; ie: for resuming a simulation, only binary sauv files are accepted for this discretization.
07/03/24 (TRUST) New Keyword : Possible to use "Unite" keyword in Definition_champs with Transformation and Morceau_Equation to specify the unit of the field (specified unit will be written in post-processing files instead of "??")
06/03/24 (TRUST) New feature : Implementing ICoCo resetTime() method allowing to reset the time origin during the computation. For now previous post files are overwritten by default.
