Dear Alexander, in gromacs you have lots of implemented tools for analysis like to compute energy between surfacant and surface by energy groups, tilt angle, order parameter, angle distribution,... But I would suggest you first to look in previous publication connected with your studies, that coul

2016-03-19 Thread Josip Lovrić
Potential energy for one atom is not well defined physical quantity as far as I know, you can only calculate potential energy for at least two body (atoms). You need to give more details about what you want and I do not know what LAMMPS do. Josip 2016-03-18 11:03 GMT+01:00 张正财 : > > Subject: Re:

Hello, I am also interested in tabulated potentials and I am working to implement it in my program. I am interested do you think is it possible to put parameters (A, B, C) in to the functions h(r) and and g(r) and give value with parameters in the table and in the topology just set parameters 1. I
