Hi,
if you do not set a seed, Espresso and the random numbers provided by Espresso in TCL (by the t_random command) behave deterministically, which means that if you do not set a different seed, the script will produce the same output. I am not sure how rand, which is provided by TCL behaves.
If you are not sure about PRNGs and their meaning for MD simulations you should look that up in a standard textbook like Frenkel and Smit.
Hope that helps,
Florian
Hi all!I have this strange problem with my code. Whenever I am running a code, it is giving me the exact same output, i.e. the position and velocity of each particle at each time step coming to be identical from my previous run. I have changed the name of the input and output files, but every time I am seeing the same problem. If you have any solution regarding this problem, please suggest.Regards,Nairhita
