v1.9.5
b306b46

TrioCFD (previously named "Trio_U") is the Computational Fluid Dynamics (CFD) code
based on the TRUST platform.

It offers, in addition to TRUST modules, different physical modules such as:

  • Turbulence LES & RANS models
  • Front-Tracking
  • Radiation
  • ALE for fluid-structure interactions
  • Turbulence (RANS) with multiphase problems

This software is OpenSource (BSD license).

New TrioCFD version released v1.9.5

1. What's new ?

  • Front Tracking discontinu : Syntaxe in datafiles is now similar to TRUST/TrioCFD datafiles:

    • Equations to be solved in a Front-Tracking-discontinu problem should not be read and associated to the problem. It should be read at the begining of each problem in a solved_equations bloc.
    • Medium (Fluide_Diphasique, Fluid_Incompressible, solid, constituent, ...) is no more read and associated to a Front-Tracking-discontinu problem. It should be read at the begining of each problem bloc.
    • Gravity is no more read and associated to a medium for Front-Tracking-Discontinu datafiles. It is read directly in the medium.

  • ALE :

2. How to install ?

If TRUST-1.9.5 is not already installed, install it with:

git clone https://github.com/cea-trust-platform/trust-code.git TRUST-1.9.5
cd TRUST-1.9.5
wget ftp://ftp.cea.fr/pub/TRUST/externalpackages/externalpackages-1.9.5.tar
# or, if problem with ftp:  
# wget "https://drive.usercontent.google.com/download?id=1YrG36uK5cJoQ9gHAnilJSUjfTWnFBboJ&export=download&authuser=0&confirm=t" -O externalpackages-1.9.5.tar
tar xf externalpackages-1.9.5.tar
./configure $OPTIONS
make
cd ..

Then, install TrioCFD-1.9.5 using:

git clone https://github.com/cea-trust-platform/TrioCFD-code.git TrioCFD-1.9.5
cd TrioCFD-1.9.5
git checkout v1.9.5
source PathToTRUST-1.9.5/env_TRUST.sh
baltik_build_configure -execute
make optim debug

3. TrioCFD Release notes version 1.9.5 : Enhancements, modifications and corrected bugs since version 1.9.4 :

06/12/24 (TrioCFD) New feature : Sensibility Analisis - module based on the Polynomial Chaos Method.
06/12/24 (TrioCFD) New feature : ALE - Interface with the MFront/MGIS C++ library to integrate a mechanical behaviour for ALE grid motion
21/10/24 (TrioCFD) Bug fix : TrioCFD - 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 (TrioCFD) Minor change: TrioCFD - C++17 compilers are now mandatory
02/08/24 (TrioCFD) Keyword : FTD - keyword juric_pour_tout was obsolete and did nothing, not allowed anymore in datafiles.
25/07/24 (TrioCFD) Bug fix : FT IJK - valgrind issue in shear periodic conditions fixed
25/07/24 (TrioCFD) Bug fix : FT IJK - Performance regression since v1.9.4 ('New shear periodic conditions') fixed
25/07/24 (TrioCFD) Major Change: FTD - Equations to be solved in a Front-Tracking-discontinu problem should not be read and associated to the problem. It should be read at the begining of each problem in a solved_equations bloc. New syntax is:

   Probleme_FT_Disc_gen pb
   ...
   read pb {
      solved_equations { Navier_stokes_FT_disc hydraulique
                         Transport_interfaces_FT_disc interf
      }
      Fluide_diphasique {
          fluide0 Fluide_incompressible { mu ... rho ... }
          fluide1 Fluide_incompressible { mu ... rho ... }
          sigma ...
          gravite ...
      }
      hydraulique { ... }
      interf { ... }
      ...
   }
   solve pb

25/07/24 (TrioCFD) Major Change: FTD - Medium (Fluide_Diphasique, Fluid_Incompressible, solid, constituent, ...) is no more read and associated to a Front-Tracking-discontinu problem. It should be read at the begining of each problem bloc.
25/07/24 (TrioCFD) Major Change: FTD - Gravity is no more read and associated to a medium for Front-Tracking-Discontinu datafiles. It is read directly in the medium.
18/07/24 (TrioCFD) Bug fix : Turbulence - Fix a bug for k-omega which introduces differences between sequential and parallel calculation
04/07/24 (TrioCFD) Bug fix : FT IJK - stat_diph_gradUP_jdd1 test case in debug mode
