WebJan 1, 2012 · Abstract. In this chapter, an introduction to ab initio molecular dynamics (AIMD) has been given. Many of the basic concepts, like the Hellman–Feynman forces, the difference between the Car–Parrinello molecular dynamics and AIMD, have been explained. Also a very versatile AIMD code, the CP2K, has been introduced. WebAb initio methods, on the other hand, scale as N4, and as a result DFT calculations are faster with better accuracy. There are, of course, still major approximations that are used in DFT that affect the computing time and accuracy of molecules that are evaluated with DFT methods. The fundamental underlying mathematics of this method is the ...
