Equations of convection in a gas are analyzed and 
a computational algorithm that is efficient when the condition 
"mu gh/RT << 1" is satisfied for an arbitrary
(fairly large) temperature drop is proposed. Calculations of
convection occurring in steady nonuniform heating of walls are
performed for axisymmetric argon-containing volumes 
of different shape. Results of these calculations demonstrate the 
establishment of steady and periodic motions of the gas.
