LAMMPS fix bond/break question

Dear All,

I had a question pertaining to the implementation of the bond/break fix in LAMMPS. At any given time-step where the event is attempted, how many bonds are chosen as targets for breaking? Does the fix loop over all bonded pairs of a given type at an execution timestep or just one of the possible bonds at random?

Hi Sri,

In every timestep, the fix will loop over all bonded pairs with the given type you set in input file. A random number will be generated to determine whether the bond should be broken or not.

Hope it can help you.
