This example consists of a square 2D plate of \unit{1}{\squaremetre}
having an initial temperature of \unit{100}{\kelvin} everywhere but a none centered hot point
maintained at \unit{300}{\kelvin}. Figure \ref{fig:htm:explicit:dynamic} presents the
geometry of this case. The material used is a linear fictitious elastic material
with a density of \unit{8940}{\kilogrampercubicmetre}, a conductivity of
\unit{401}{\watt\per\metre\per\kelvin} and a specific heat capacity of \unit{385}{\joule\per\kelvin\per\kilogram}. The time step used is \unit{0.12}{\second}.
