Murnaghan equation fit code question Date: 2012/05/25 20:26 Name: Ryan Dear Dr. Ozaki, My name is Ryan a first year graduate student currently researching on boron nitride nanotubes. Recently, I was trying to calculate the equilibrium lattice constant of an fcc Au slab using openmx. According to its (openmx) manual, I can plot the energy vs the lattice constant using a program called murn.f. I have successfully compiled murn.f and created an executable file murn.x to be used in plotting but I couldn't really follow the process discussed in the 'readme' file. The openmx program has file called *.EvsLC and I assume that it is the input file in murn.x. To make things worse, I don't know what to put in the output file. I am new to computational materials research and still trying to master lots of topics in computational physics. With all these, could I possibly ask just a little time from you to discuss the process of obtaining an energy vs lattice constant plot? Thank you very much for your time Sir! Sincerely, Ryan

Firstly i do my calculations on GaAs.I want to find Bulk modulus. But when i used Muraghan fit , in output file Bulk modulus shows value ***************** Sir Please help me what should i made changes and what is the type of the input file. THanks in advance
