Hi
I followed SMD tutorial for Ubiqutine molecule and realized Temperature(TEMAVG
in log file) is getting higher. I got the following from the log file.
ENERGY: TS TEMAVG
SMD
   0 315.1040
 100 343.5757
 600 388.5298
4000 414.5304
....

How can I explain this ?
I add part of conf file for your review.. Thanks,

Taeho
