PROJECT TOPIC- FORTRAN 77 IMPLEMENTATION OF THE TRANSITION METAL MODEL POTENTIAL (TMMP) CODE: AN APPLICATION TO FCC-COBALT

PROJECT TOPIC- FORTRAN 77 IMPLEMENTATION OF THE TRANSITION METAL MODEL POTENTIAL (TMMP) CODE: AN APPLICATION TO FCC-COBALT

  ABSTRACT

A Transition Metal Model Potential (TMMP) code originally written in FORTRAN IV and designed for mainframes was modified and upgraded to a FORTRAN 77 code and adapted to run on a Personal Computer (PC). After verification, the modified code which was found to be of…
