The document cp_user_guide.pdf, recommends adding a random displacement to ions before switching on the thermostat and not to increase the temperature too much. In order to achieve a high temperature ~ 800-1000 K, the random displacement must be increased in the 1st step. Based on my microcanonical simulations, I found out that adding a very high random displacement of ~0.9-1 a.u. gives the required average temperature for my system. So, my question is: is it okay to first run a micro canonical simulation with such a high random displacement to achieve a temperature close to the required (high) temperature and then turning on the thermostat?</div><div class=""><br class=""></div><div class="">Thank you,</div><div class=""><div class="">
