Tdyn

Tdyn is an environment for computational fluid-dynamics (CFD), multi-physics simulation, and fluid-structure interaction calculations, based on the leading stabilized finite element method (FIC-FEM).

Tdyn includes different modules that allow to solve Heat Transfer in both solid and fluids, Turbulence, Advection of Species in fluids and solids and Free Surface problems using the same stabilised scheme mentioned above. Tdyn also offers advanced solvers for beams, shells and solid structures, and includes cutting-edge tools for solving fluid-structure interaction (FSI) problems.

The different analyses available in Tdyn are fully integrated in an advanced graphic user interface (GUI), for geometry and data definition, mesh generation and post-processing the analysis results. The Tdyn GUI uses a versatile tree-like interface for data managing, allowing an easy control of the whole process of entering the analysis data.

Tdyn offers several integrated modules, for a wide range of engineering problems:

  • RANSOL

module features the latest technology for solving real fluid flows in 3D (transient or steady), including turbulence effects. The fluid models available allow to solve from fully compressible to incompressible fluid flow problems and porous media flows.

  • HEATRANS

module is able to solve complex forced, natural, and mixed convection heat transfer in fluids and conduction in solids (conjugated heat transfer).
  • ADVECT

for advection-diffusion-reaction of several chemical species, including effects of physical processes as depositions.
  • FSURF

includes two advanced algorithms for solving problems with free surface (Transpiration technique and Overlapping Domain Decomposition Level Set Method).
  • URSOLVER

for user defined partial differential equations (PDE) problems.
  • ALEMESH

offers several mesh updating strategies: prescribed / free bodies movement with automatic mesh updating, explicit 3D mesh movement via user functions and combinations of these strategies.
  • RAMSERIES

features an advanced environment for structural analysis, based on the latest Finite Element Method technology. It includes advanced tools for fluid-structure interaction calculation. For further information, please visit RamSeries.
  • SEAFEM

is an advanced tool for analysing seakeeping problems. For further information, please visit SeaFEM.

More detailed information about Tdyn features and system requirements can be found at Tdyn Technical Specifications, in the Support page, and in the Release Note.

The latest Tdyn version can be download from Download. This version is free, but limited in the number of mesh nodes that can be used. An 1 month password for demo purposes, that activates all the capabilities can be obtained at Passwords.
