One of them has block which emits a uniform heat flux. The external pressure is the same at both top and bottom of the plate so the flow is driven by buoyancy alone. PLANT is used to introduce GROUND codings for non-uniform buoyancy forces. ENDDIS PLANTBEGIN **Boussinesq approximation for buoyancy force.
