[Pw_forum] tempp shoot up problem in CP

[Amar Singh]

Dear Friends,​I am trying to do CP-MD on a small unit (10 atoms, to start with) following the steps recommended in different examples/user guide. Everything converges fine for achieving electronic ground state and ion relaxation. As soon as I start CP dynamics with verlet, tempp starts to shoot up and never get close to 0K.​I tried varying  emass/cutoff/ but did not help much. Will be thankful for any suggestion. thanksAmar​DMGRU, Chennai
