<div>Hi all,</div>
<div> I have performed total energy calculation for Al as a function of lattice parameter. then i fit those data to murnaghan equation of state and got bulk modulus. when i use method of hydrostatic strain and got bulk modulus, it is much smaller than the one obtained by fitting E-a curve to murnaghan eos. So, which one is more reliable, since, bulk modulus obtained by fitting to mur. eos is quite near to experimental data. and which one should be used to determine other elastic stiffness constant ?</div>
