Dear all,
I want to know the meaning of the 'seed' option in velocity command. There is no explicit explanation about that in manual.
Thanks,

Dear Chol-Jun:
It’s the seed to the random number generator, which LAMMPS uses to assign velocities according to a given probability distribution (Gaussian or uniform in the case of LAMMPS). If you need more information on how those work, you should look at a reference like Numerical Recipes.

From the doc page:
create args = temp seed
temp = temperature value (temperature units)
seed = random # seed (positive integer)
Just use a random big integer, like 12345
