Demonstration of an interactive instantaneous runtime simulation of a 2D supersonic flow. With a pen, I draw some blunt bodies that create shock waves. The simulation is performed on the GPU of a laptop. A pen device allow me to "draw" at the screen, as if I had a mouse. The computational grid is 768x512, I use an explicit Finite Volume scheme to discretize the compressible Euler equations. This was presented at the Workshop on "Trends in Numerical and Physical Modeling for Industrial Multiphase Flows", 24-28 sep 2012, IESC Cargèse, see http://www.polymtl.ca/gch/cargese2012/. We are ready today for new innovative ways of exciting educational projects with this kind of simulation tools. This work is partly supported by the ENS Cachan Farman Institute (http://www.farman.ens-cachan.fr ) and by NVIDIA under an NVIDIA Equipement Grant (2011). It is also an investigation work toward the french "Equipement of Excellence" named DIGISCOPE http://www.digiscope.fr , cluster of high-end interaction, visualization and collaboration facilities over the Paris-Saclay University. 

Special thanks to Mathieu Peybernes for having filmed the demo :)

Instant Navier-Stokes flow simulation at high Reynolds on GPU. Here a stabilized Lattice Boltzmann BGK method is used.

Air-water two-fluid flow. Collapse of a water column impacting an obstacle. Here a Lagrange-remap finite volume scheme is used, with a low-diffusive interface capturing approach. Collaboration with Aude Champmartin.

Instant computation of unsteady 2D incompressible Navier-Stokes equations with human interaction using a stabilized Lattice Boltzmann method (LBM) and openGL for visualization and user interaction. Performed with a simple video projector, a standard laptop and a simple tracking device !! The computation is done in parallel on the GPU (here a NVIDIA GTX 460M). The pen pointer allows for adding wall obstacles into the computational domain on the fly (immersed boundary method).

Air-water Rayleigh-Taylor instabilities, grid 400x400 using a Lagrange-remap Finite Volume scheme and an anti-diffusive strategy for capturing the interface (related are Lagoutière-Després 2002 and Kokh-Lagoutière 2010). About 7 day of computation (sequential code). GPU code porting is intended to compute the same problem within half a day.
