This model treats the free convection and heat transfer of a glass of cold water heated at room temperature. The flow is modeled with the application mode for non-isothermal flow and the temperature field using the convection and conduction application mode in the chemical engineering module. Initially, the glass and the water holds 5 °C (brought out from a refrigerator). It is then put on a table in a room at 25 °C.

Streamlines of the velocity field at four output times. The buoyancy driven flow induces recirculation zones visualized by the streamlines in the figure.
