I am looking for more discussion. about a phrase for orientorder Threshold, in lammps documentation. its described as ‘threshold = minimum value of the product of two “connected” atoms’ but I am unable to find some discussion. about it in documentation, may be my question is so brief, but can anyone comment on this what is exactly meaning of this product of two atoms ?could be a vector product but what we are giving actually to compute when. we give their product
You need to read the documentation more closely for compute coord/atom and compute orientorder/atom. All of the information is in those two pages.
Granted, the snippet at the top of the page should probably be changed to something like
threshold = minimum value of the scalar product of Ybar_lm of two "connected" atoms
But all the relevant information is described later in the page.
