Dear Forum,<br><br>It try to heat vc-md calculations.<br>But I can not reach the target temperature.<br>When I set tempw = 100 , it will stable at about 38K<br>When I set tempw=1000, it will stable at about 400K.<br>I pasted part of my input bellow.<br>
Any one have some idea?<br><br>Thank you very much.<br><br>'''<br>&control<br> calculation = 'vc-md' ,<br> prefix = 'alpo4-10' ,<br> restart_mode = 'from_scratch' ,<br> nstep = 30000 , <br>
