bond/break

Hi,

I have some queries regarding the bond/break command .

1. As it is documented in LAMMPS site :"This fix is part of the MC
package. It is only enabled if LAMMPS was built with that
package....Currently, there are 2 restrictions for using this fix".

So what exact package is required for this command to work with ?

2. Now,say,I have a system where 'the no of bond types'='no of bonds'.
   And moreover all the bonds have different bond length.

For this case if I want to impose bond/break, I have to mention the
'bond-type' in the fix. Basically it has to be executed over all bond
types.then what value have to be written ?

Any comment is welcome.

Thanking you,

Best,

You need the 'mc' package. For instructions about how to build LAMMPS with optional packages (Linux):

You can also play with 'make' in your source directory.

I don't know 'bond/break', so I'll leave it to someone else to answer point 2.

For the second answer,
If you want to all bond types to be eligible then have the fix multiple times with different values of bond_type.
