<div dir="ltr">Dear all<br>I am performing a molecular dynamics with external pressure .I used calculation=vc-cp and I added <br> &cell <br>cell_dynamics='pr' <br>press=200,<br><br>now I've got two question:<br>
1. econt is constant during this simulation or not?<br>2.how can I control the temperature of the system?how can I find correct fnosep?<br> &electrons<br> emass = 500.d0,<br> emass_cutoff = 2.5d0,<br> electron_dynamics = 'verlet',<br>
electron_velocities='zero',<br> /<br> &ions<br> ion_dynamics = 'verlet',<br> ion_velocities='zero',<br> ion_temperature='nose',<br><span style="background-color: rgb(255, 255, 255);"><span style="color: rgb(255, 0, 0);">tempew=300,</span></span><br style="background-color: rgb(255, 255, 255); color: rgb(255, 0, 0);">
