<div>Dear Users and Prof.</div>
<div> perhaps a stupid questions!</div>
<div> I am interesting at the dielectric coefficient of materials, I know the Wien2k can give the dielectric tensor by this flow:</div>
<div> for no-magnetism system:</div>
<div> run_lapw </div>
<div> x kgen</div>
<div> set "TOT" to "FERMI"</div>
<div> run_lapw -s lapw1 -e lcore</div>
<div> x optic</div>
<div> x joint</div>
<div> x kram</div>
<div> and the dielectric tensor will save at case.epislon</div>
<div> BUT , how can I get the dielectric constant from this? Thank you very nuch!!!!</div>
