It should be straightfoward to plug in alternate engines, although we haven't done so. The input to the engine is the initial world transform of the body, its collision geometry, mass, friction, ...
Molecular collision dynamics investigates how atoms and molecules interact during collisions, a process central to chemical reactivity and energy transfer. At the heart of these studies are potential ...
High-order harmonic generation (HHG) provides a main route to generate attosecond (10-18 s) pulses, which have been considered “the world’s fastest film camera” for imaging the movement of electrons.
