Motivation : In Space Grains WP3, the convection of grains is studied in common cells (2d and 3d). The relevant parameters which control convection in zero g are not yet established. The Space Grains project will allow scientists to perform long runs and extensive study of this phenomenon. A specific cell (asymmetric cell) will be proposed in a second step of the project.

The movie below illustrates the dynamical clustering under asymmetric energy injection. The moving walls oscillate at different amplitudes.  The cluster (yellow colored grains) moves close to the cold wall.
