This way you can reduce the cutoff energy (search inside the PSP files the largest corresponding value among the PSP: this is the lowest value you should use, then increase it a bit, make tests…).</div><div class="">2) The mixing_beta parameter may be too large: try 0.2 or 0.25</div><div class="">3) If you have a metal or semi-metal, degauss may be toot small. Try between 0.05 and 0.1 (0.1 is large).</div><div class=""><br class=""></div><div class="">HTH,</div><div class="">Best,</div><div class="">Pascal</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div class="">
