In this short note, we describe a steady-state solution of fully compressible convection which could be used for comparisons with those obtained with the lattice gas approach. This solution has been obtained with a pseudospectral code. It consists of two steady rolls at a maximum Mach number of 0.60 and at a maximum Reynolds number of 700. Slip boundary conditions for the velocity have been used. Regarding the temperature, we used a radiative boundary condition at the upper boundary of the fluid layer and fixed temperature at the lower boundary.
