Hi Folks<div><br></div><div>I am new to this field, learning it. We are carrying out AIMD simulations using cp2k of water solvated acidic-basic membrane systems. I have a question as follows:<br><div><br></div><div>For three different configurations of atomic nuclei, initial potential energy as calculated by cp2k is almost same around -3128 Hartree. </div>
<div><br></div><div>These configurations are </div>
<div><br></div><div>1. Configuration at the end of classically equilibrating the system with DREIDING hydrogen bonding potential ON</div><div>2. Configuration at the end of classically equilibrating the system with such potential OFF</div>
<div>3. Initial configuration BEFORE any classical equilibration. </div><div><br></div><div>Isn't the potential energy supposed to vary with change in nuclear positions? </div><div><div>If case 1 and 2 are same, fine a possibility, but even case 3 is same, which is very strange. It's a system completely away from classical equilibrium. </div>
<div>
