Overview
The Angle node calculates the angle, in degrees, between three provided sites $i$, $j$, and $k$, which are referenced from
Select
nodes.
Description
Angle is one of several calculation nodes that determine and store a numerical result, ready for retrieval and use by other nodes in a procedure.
Angle determines the angle $i$-$j$-$k$ between the selected sites $i$, $j$, and $k$, obeying minimum image distances if the encompassing box is periodic. The resulting value is measured in degrees.
