check/timestep/gran expressions refs and doc

Submitted by SergeiD on Wed, 05/04/2011 - 11:41

Hello.
Is there a refs. where rayleigh_time and hertz_time expressions are derived?

And more, I see an error in the check/timestep/gran documentation.
In the doc:
dt_r =PI*r*sqrt(rho/Y)/(0.1631*n+0.8766),
But in code instead Y used shear_mod.

Also, for dt_h. In doc:
dt_h =2.87*(m_eff²/(r_eff*G_eff²*v_max)^0.2.
But in code instead G_eff used E_eff.

Also, I will correct the "frictionflag" in the pair style to "friction_damp_flag" as it controls tangential damping and rolling friction
