Dear Pwscf users,<br>I have done the vc-relax calculation of ScSb. At the end of the file, I am getting relaxed cell volume, CELL_PARAMETER AND relaxed atomic position and pressure P= -0.32 kbar<br><br>If once again I put all the above parameters in the input file and do the vc-relax calculation, then in first scf step I must get a pressure of -0.32 kbar.<br>
But this is not the case. The pressure changes to some other value (-10.38 kbar).<br><br>So my question is why this happens? Why the pressure again increase or decrease?<br><br>regards<br clear="all"><br>-- <br>Bipul Rakshit<br>
