  We study the formation and the dynamics of a shock wave originating from the
collision between two ultracold clouds of strongly interacting fermions as
observed at a lower temperature in an experiment by Joseph et al. [Phys. Rev.
Lett. 106, 150401 (2011)]. We use the Boltzmann equation within the
test-particle method to describe the evolution of the system in the normal
phase. We also show a direct comparison with the hydrodynamic approach and
insist on the necessity of including a shear viscosity and a thermal
conductivity term in the equations to prevent unphysical behavior from taking
place.
