<div>Hi Pw_forum folks,</div>
<div><br>
</div>
<div>I'm new to Quantum Espresso, but I have checked the archives and I don't think this question has been asked (at least not this way). Here goes:</div>
<div><br>
</div>
<div>I'd like to perform a series of vc-relax calculations on a crystal lattice such that each time I increase the amount of applied strain in a given direction (via the CELL_PARAMETERS), from one calculation to the next I reuse the other, unconstrained CELL_PARAMETERS
and the ATOMIC_POSITIONS. This way, my Poisson contraction and non-uniform relaxation of the atoms is done gently, rather than restarting each calculation with the same 'unrelaxed' ATOMIC_POSITIONS. I'm hoping that a few of you have done something similar
and have a script or suggestions for carrying-over the CELL_PARAMETERS (those I'm not fixing) and ATOMIC_POSITIONS from one calculation to the next. If so, please respond.</div>
<div><br>
</div>
<div>Thanks!</div>
