I am new to LAMMPS.
I installed LAMMPS( parallel) successfully.
Now I am using Crack propagation example.
I need long simulation ( ie each run should take 40 mins to 2 hrs).
SO I want to increse the Number of atoms ( without altering the number of steps).
Which parameter I have to change in crack.in file.
and Also want to know, how those parameters involved in calculation of number of atoms.
Thanx in advance
