A computer-algebraic investigation of an oscillating boundary layer

Bénard (square shaped) cells in silicon oil

The shape of the inner cells is strongly influenced by the geometry of the boundary of the vessel

Instead of hexagonal cells (Bénard cells) in the case of a circular boundary
here the fluid organizes in form of square cells.
