<DIV id=RTEContent>Dear Wien users,</DIV> <DIV> I'm doing structural optimization or a surface using the command:</DIV> <DIV> </DIV> <DIV>min_lapw -j "runsp_lapw -I -i 100 -fc 1.0", for the topmost two layers, however my calculations stop with forces larger than 1 , about 15 or sometimes more , so what could be the reason of stopping before convergence is obtained?</DIV> <DIV> </DIV> <DIV>thank you</DIV> <DIV>Hazem</DIV> <DIV> </DIV><p>
