<div>Dear all,</div>
<div> I am doing total energy calculation for a system having two atoms per unit cell. When doing it I am getting converged total energies upto lattice constant a=7 bohr. When doing calculation for higher values of a=8 bohr, I am getting following message.</div>
<div> </div>
<div>convergence not achieved.</div>
<div>end of calculation. </div>
<div> </div>
<div>and as a result, i am not getting value of total energy.</div>
<div>so, help me</div>
<div> </div>
<div>thanks in advance</div>
