[ESPResSo-users] Stress Tensor

[Muhammad Anwar]

Hello,
Dear Users,
I am using espresso (ESPResSo-3.1.1-418-g057595e-dirty-git) and 
computing the stress tensor, I compute total pressure tensor for Lennard 
jones fluid in two way;

 set p_tensor_full [analyze stress_tensor];
 set total [lindex $p_tensor_full 0]
 set p_tensor [analyze stress_tensor total]

I find different results for both. Are not they same quantities? If not 
what is the difference between them because from user guide it look like 
they are same.

I am attaching minimum script to check.

Thanks

Best Regards,
