<div dir="ltr"><div>Dear all developers and Users,<br></div><div>I was doing Car-Parrinello Molecular Dynamics for the optimization of a structure. For this purpose i <span class="">compute the ground state wavefunction using cp.x which gives the convergence achieved for system relaxation keeping 'ions' and 'cell' sections with no dynamics.<br>
</span></div><div>Then i put the calculation field 'vc-relax' instead of 'vc-cp' because i wanted to calculate the optimized structure keeping 'ions' and 'cell' sections with 'damp' and 'sd' dynamics. i am curious to know whether this procedure which i was opted is right or not? <br>
</div><div></div><div>As cp.x(vc-relax) has a one k-points(Gamma) so results obtained for cell parameters of the optimized structure is reliable as obtained from pw.x (vc-relax) or not?<br></div><div>I am looking forward for your kind attention and help regarding this issue.<br>
