LIN HOME PAGE

The Laboratory of Computational Engineering (LIN) is a research and teaching laboratory within the Institute of Mechanical Engineering (IGM) of the School of Engineering (STI) at the Swiss Federal Institute of Technology - Lausanne (EPFL). The LIN is involved in a wide range of basic and applied research in computational science and engineering with an emphasis on numerical fluid mechanics.

Fundamental and applied research, as well as teaching, are undertaken within three main themes:

• physical and numerical modelling
• hardware and software resources
• complex multiphysics applications

Physical modelling activities are focussed on the understanding of complex (e.g. unsteady, turbulent, 3D, reacting) compressible and incompressible flows, including non-Newtonian fluids and particulate flows. The numerical simulation of these flows is performed using a variety of numerical methods (e.g. finite element, spectral element, lattice Boltzmann and discrete element methods). To perform state-of-the-art simulations, attention is given to the hardware and software resources required; the LIN is thus strongly involved with the Pleiades cluster, grid computing initiatives and scientific visualization. Finally, these basic aspects are employed for complex multiphysics simulations, often involving the coupling of different methodologies (fluid-structure, fluid-particle, plasma-aerodynamics, etc.).
