So far, when I calculate equation of state, I used series of relax calculations. </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
1) Download crystal structure. </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
2) Run relax </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
3) Run vc-relax based on result of 2)</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
4) Get crystal coordinate (= fractional coordinate) of 3) </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
5) Based on optimized cell info from 3), calculate cell parameters (or cell dimensions) for each volumetric expansion / compression. (ex: from 80% to 120% of volume for every 5%) </div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
6) Run series of relax calculation using 4) and 5). Use the same crystal coordinate, just changing cell parameters (or cell dimensions). </div>

Is there any other way to calculate equation of state of crystal unit cell in QE? </div>

Or, is there any automated way / option for the equation of state calculations in standalone QE or with QE + third party free softwares? </div>
