coefficientFriction in hertz model

I don't get where the coefficientFriction is used in gran/hertz/history formula, according to the formula given in pair_gran.html file there is no need to this quantity.

The coefficient of friction (xmu) is used to fulfill max(Ft) = xmu Fn, and the tangential overlap is truncated.
If you want to know the details, check out pair_gran_hooke_history.cpp
