      <div dir="ltr">Hello
        <div>I am a new user of WIEN2k, and I am using WIEN2k_21.1 on
          the slurm cluster (intel) system.  I have two questions with
          regard to proper usage of wien2k for DFT calculations:</div>
        <div><br>
        </div>
        <div><b>1</b>. I performed volume optimization for different
          exchange functionals (GGA and LSDA) and I got different
          optimized values, which is not a surprise for me. My question
          is: Do I need to perform volume optimization again after I add
          spin-orbit coupling as a second variational method to proceed
          with further calculations?</div>
        <div><br>
        </div>
        <div><b>2</b>.  I calculate fermi surface, for spin orbit
          coupling, using the following command in my slurm job script
          to run parallel with:</div>
        <div><b>x lapw1 -p<br>
          </b></div>
        <div><b>x lapwso -p<br>
            x lapw2 -so -p -fermi</b></div>
        <div>But when I visualize the fermi surface/s on XCrysden
          (version 1.6), it seems like I am getting fermi surfaces for
          non-spin-orbit calculations only, that is XCrysden is reading
          data from case.output1. Please advise me on how to properly
          visualize fermi surfaces that are generated using the above
          three commands.</div>
        <div><br>
        </div>
        <div>My system is non-magnetic (so performing non-spin-polarized
          calculations) and the system contains heavy atoms, so I need
          to incorporate spin-orbit coupling in the calculations. </div>
        <div><br>
        </div>
        <div>Thank you so much for your advice and time.</div>
