Telemac3d solves the Navier-Stokes equations along a three-dimensional (3d) computational grid using a finite element scheme. Telemac3d mounts the tetrahedral 3d mesh from a triangular 2d mesh in a user-defined number of vertical layers. The number of vertical layers to use is defined in the TELEMAC steering (CAS) file. This tutorial walks through the creation of a 2d mesh with SALOME-HYDRO along with boundary and control files. The tutorial also features running a Telemac3d simulation with the files created and plotting results with the ParaVis plugin of SALOME-9.8.0 (a tweaked version of ParaView that is able to read MED files).
A Telemac3d simulation requires similar input files as a Telemac2d simulation and this tutorial uses MED files to define the geometry. In particular, the following files will be created:
Software: SALOME-HYDRO’s HydroSolver module (alternatively: Fudaa PrePro) or any text editor)
Software: SALOME-HYDRO’s Geometry and Mesh modules
Software: SALOME-HYDRO’s HydroSolver module
Unsteady flow conditions
Prepare with any text editor
Optional files such as a friction data file or a liquid boundary file can also be implemented, but are not featured here. Read more about input data files and their formats in the TELEMAC introduction.
This chapter provides two tutorials for 3d modeling with TELEMAC featuring two mesh file formats that are implemented in TELEMAC:
A 3d steady hydrodynamic simulation with a standard SLF geometry file is set up an run in the Telemac3d (Standard) tutorial.
A 3d steady hydrodynamic simulation based on the MED file library is set up an run with the SALOME software (Linux only) in the Telemac3d with Salome-Hydro and MED tutorial.
