"I think the law of virtual crash is Runge-Kutta"
Answer/Comment:
Not sure what you meant by "I think the law of virtual crash is Runge-Kutta' Runge-Kutta is an integrator used in many simulation programs.
For exampe in the HVOSM simulation program, from page 116 of the original manual:
The numerical integration routine used provides the user with an Runge-Kutta classical fourth-order method as modified by E, K. Blum or the Adams-Moulton predictor-corrector method using the Runge-Kutta method for starting the process.
For more on HVOSM see Ray McHenry's award winning IME paper from 1969 on HVOSM:
In Virtual Crash (if you were referring to that program?), for vehicle spinouts, they might be using Runge-Kutta integration (you can check with them) to integrate their equations of motion.
However for simulating collisions:
They are strapped by the simplification of instantaneous momentum exchange for collision interactions, like pc-crash
Both programs require the user to specify a very subjective point and angle for the instantaneous momentum exchange!
