<div><div>Dear espresso users!</div><div><br></div><div>I'll try to calculate work function under the finite electric field using tefield flag.</div><div>But I didn't obtain any differences with the case without electric field, I didn't notice any inluence of sawlike potential.</div>
<div>I attached my input file. Could anybody told me, what's wrong?</div><div><br></div><div>&CONTROL</div><div> calculation = "scf",</div><div> pseudo_dir = "./",</div><div> outdir = "./",</div>
