I put this pressure (7 kbar) on my structure and let it relax, the final
pressure is calculated to be 6.57 kbar as the following. Therefore it is
not exactly 7 kbar.<br></div><div><br></div><div>Computing stress (Cartesian axis) and pressure<br><br> total stress (Ry/bohr**3) (kbar) P= 6.57<br> 0.00004467 0.00000000 -0.00000000 6.57 0.00 -0.00<br> 0.00000000 0.00004467 -0.00000000 0.00 6.57 -0.00<br> -0.00000000 -0.00000000 0.00004467 -0.00 -0.00 6.57</div><div><br></div><div><br></div><div>MY QUESTION: Which pressure should I report on my paper; 7 kbar or 6.57 kbar?</div><div><br></div><div><br></div><div>Any comments would be appreciated.<br><br></div><div>Best regards<br></div><div>Mohaddeseh<br></div><br clear="all"><br>-- <br><div dir="ltr" class="gmail_signature">---------------------------------------------------------<br>Mohaddeseh Abbasnejad, <br>Assistant Professor of Physics,<br>Faculty of Physics, <br>Shahid Bahonar University of Kerman,<br>Kerman, Iran<br>P.O.
