Dear All,
I want to simulate a two-dimensional colloidal system of particles interacting through the Debye-Hückel potential. But I am also interested in applying an external field that mimics a substrate.
Each particle is subjected to an external potential like this,
Uext(xi) = strength of the external potential * sin ( constant * x(i) )
If I understood well, I can not use the ext_force command neither the tabulated potential.
I would really appreciate any suggestions for the implementation.
At this moment I have only a very simple idea of setting integrate to 1 and then apply the external force in x-direction in each step.
However , I think this is highly inefficient and makes the simulation runs slowly
Thanks in advance.
