Friction and frictional heat generation

This normal force leads to a friction force $F_f$ which equals


\begin{displaymath}
F_f = \nu \: F_n
\end{displaymath}

where $\nu $ is the friction coefficient (see contact_friction. The friction force causes heat generation rate $Q$:


\begin{displaymath}
Q = \eta \: F_f \: v_f
\end{displaymath}

where $v_f$ is the slip velocity, and the factor $\eta $ is a user specified factor which determines which part of the frictional energy loss is transformed into heat ($\eta $ is between 0 and 1; see contact_heatgeneration).
