Re: [ESPResSo-users] time dependent force

[Jiajia Zhou]

Thanks for the reply. I would like to change the force every single
time step. To do this in the tcl level, I think the force are
calculated twice for every time step (am I correct?), so I can save
some time by implementing in the c level.

Thanks!
