Popis:	We present the numerical investigation of Rayleigh‐Benard convection (RBC) in a slot whose bottom wall is subject to a long‐wavelength heating and the upper wall is isothermal. It is shown that multiple flow structures associated with the same conditions can be produced by changing the history of the heating; this history can be controlled by using different initialization conditions, different continuation strategies in the parameters space as well as by using different numerical solvers. The observed flow structures can be categorized into two generic groups, i.e. symmetric and asymmetric flow structures.
