Hello,<div><br /></div><div>I am trying to run a QM/MM/MD simulation on a metalloenzyme containing Zinc and a substrate. After about 3000 fs of simulation time, the aspartate seems to show a weird displacement in atoms.</div><div><br /></div><div>I have tried changing both colvar constraints and QM box sizes to test if they are causing the error, but the error keeps popping up. Is it a problem of the quadratic walls and K under &WALLS?</div><div><br /></div><div>Any guidance is appreciated.</div><div><br /></div><div>attached screenshots and Monitor file. </div><div><br /></div><div>Regards</div><div>Parth Rathee</div>
<p></p>
