SYRTHES is a general thermal software dedicated to transient thermal simulations in complex solid geometries. EDF's R&D developed the software that can be used for a range of problems: nuclear (lifetime, nuclear waste disposal, new concepts, fuel transportation, etc.), electricity (transport, electromechanical devices, etc.), building efficiency, material physical properties, etc.
THREE THERMAL PROBLEMS SOLVED
SYRTHES solves thermal transient in 2D, 2D axi and 3D coordinates systems.
The solid properties and source terms may vary with respect to time, space, temperature, etc. The conductivity behaviour may be either isotropic, orthotropic or anisotropic. Classical boundary conditions are available and may vary with respect to time, space and temperature.
- conductivity behaviour: physical properties of the solids or the source terms can vary over time, space, and local elements like temperature. Conductivity can be either isotropic, orthotropic or anisotropic
- diverse limit conditions are available and can be varied over time and local elements: enforced temperatures, flow, exchange, contact resistance, or infinite radiation
- wall to wall thermal radiation (non-participating medium) is also available in 2D, 2D axi and 3D allows shadowing effects to be automatically performed in complex geometries
- heat and mass transfers
- SYRTHES coupled with the CDF code developed by EDF: Code_Saturne
- SYRTHES 4.3 is compatible with Code_Saturne 4.x
- SYRTHES 4.1 is compatible with Code_Saturne 3.x
WHICH NUMERICAL METHODS?
- conduction resolution is based on a finite element approach (2D triangles and 3D tetrahedrons)
- radiative aspect resolution is based on a radiosity approach (2D segments and 3D triangles)
Standard mesh files accepted for SYRTHES are:
- SALOME file (extension .med)
- SYRTHES file (extension .syr: ASCII file containing the needed geometrical information to perform a study)
- ideas file (universal file with a .unv extension)
- GAMBIT file (extension .neu)
- GMSH file (extension .msh)
- Simail file (extension .des)
The code is currently unavailable on Linux and Windows platforms.
