Motivated by the hadronization properties of heavy-ion collisions,
we study the thermalisation properties of field theories.
First of all, we present our recent observations regarding the local energy-density
and momentum distributions in the classical $\Phi^4$ theory.
As this theory exhibits interesting features regarding these questions,
we continue the research by the MC simulation of the SU(3) Yang-Mills theory
and we intend to investigate further in more complicated theories.
