<DIV>Dear Wien2k users,</DIV> <DIV> </DIV> <DIV> recently, I have done some AFM calculations, but I have somewhat confused </DIV> <DIV>by the recommedation below from the Wien2k userguide</DIV> <DIV> <FONT color=#ff0000>" It is recommended that you save your work(lapw_save) and check the results by continuing with a regular runsp_lapw. If nothing changes(E-tot and other properties),then you are ok."</FONT></DIV> <DIV><FONT color=#ff0000> </FONT><FONT color=#000000>why E-tot and other properties should not change by continuting a regular runsp_lapw? if it is truely so, will it be conclude that the final converged result has dependence of the initial given condition, not uniquely determined???</FONT></DIV> <DIV><FONT color=#ff0000></FONT> </DIV> <DIV>Any suggestion will be greatly appreciated! </DIV> <DIV> </DIV> <DIV>Best regards,</DIV> <DIV>Iphyboy</DIV><p>
