Force Algorithms


Hi,

In the specification below, l use f_5[1] f_5[2] f_5[3] to obtain total forces from atoms.
Please, which algorithm is used for the force evaluations? Can you direct me to a reference paper?

Is it like that used in the paper:


“Establishment of a cutting force model and study of the stress–strain distribution in nano-scale copper material orthogonal cutting” by Lin et al (2007)



The International Journal of Advanced Manufacturing Technology



Volume 33, Numbers 5-6 (2007), 425-435

the *total* force is determined through an algorithm
commonly known as _addition_. i am sorry to not
be able to give you a reference, i suggest you ask
your local elementary school teacher.

how the _individual_ force components are determined,
you have to look up yourself, since they depend on what
potential you chose and you are not providing that information.

surely you cannot expect people to read a paper
to give you a "yes/no" answer on a trivial sounding
question like yours. at the very least you have
give a summary of what is so special about the
"algorithm" described in this paper.
