  We computed the self-organisation process of a monodisperse collection of
spherical micrometric particles trapped in a two-dimensional (2D) thin liquid
film isothermally dried on a chemically inert substrate. The substrate is
either flat or indented to create linear stripes on its surface. The numerical
results are illustrated and discussed in the light of experimental ones
obtained from the drying of diamond particles water based suspension ($d_{50} =
10 \mu m$) on a glass substrate. The drying of the suspension on a flat
substrate leads to the formation of linear patterns and small clusters of
micrometric particles distributed over the whole surface of the substrate,
whereas the drying of the suspension on a indented substrate leads to the
aggregation of the particles along one side of the stripe which has a higher
roughness than the other side of the stripe. This is an easy experimental way
to obtain colloidal selforganized patterns.
