CFD Labs


By Dr Annie Claude BAYEUL

The aim of the CFD labs is to practice on a commercial software STAR.AN CCM+ which includes:

  1. Generation of the geometric model of the case under investigation (importation of a previously prepared CAO model or directly creation using the 3D-CAD module within the code)
  2. Generation of the mesh (mesh models, mesh parameters, influence on results)
  3. Modelling physics
    • Space, time and eventually motion
    • Materials (gas, liquid, solid)
    • Choice of solver (segregated or coupled flow)
    • Equation of state
    • Viscous regime: inviscid, laminar, turbulent (selecting a turbulence model for a RANS approach for steady calculation or detached eddy simulation or large eddy simulation for unsteady calculation)
  4. Implementation of boundary conditions
  5. Influence of the solver and of the models on the results
  6. Basic visualization and post-processing of the results

The main objective for students is to learn the sequences of steps required to perform a numerical simulation on a complex geometry using commercial software. This will also provide students with an opportunity to study the influence of the large number of parameters involved in a numerical simulation.
