Hey, guys,

I have a problem to get the critical timestep, could you please give me
hand?
if I need to calculate the critical time step for each time steps, how can I
calculate it?
>From papers, I found that equation is:
critical_time_step=2*sqrt(mass/k),

my questions are:
1. is the mass the particle mass?
2. k here is kn or ks or some other value else?
3. I need to calculate all the critical_time_step for each particle, and
then use the mininum one, right?

and I hear that in the past, the critical_time_step need to calculated at
each timestep, then why and how?
if I do it at the beginning and get the mininum critical_time_step, and then
keep it as the critical time step for the overall simulation, will it work?

Thanks for your help.

Kan.
