This example is a benchmark problem for compressible thermal convection.
 The initial temperature has a single spherical harmonic perturbation.
 The numerical solution of the velocity and stress fields can be compared
 with semianalytical solutions.
 The Stokes solver is benchmarked and validated.

However, no analytical solution exists for the benchmark on the energy
equation solver, which is nonlinear.
