<div>Hello,</div>
<div dir="ltr"><span style="font-size: inherit;"><br>
</span></div>
<div><span style="font-size: inherit;">I am performing an optimization of an adsorption of a molecule (CH4) on a slab (WN). This will allow me to find the adsorption energy of CH4 on the slab. The layer where the molecule is adsorbing is not fixed; it can move.
Should I fix my CH4 atoms or let them move?</span></div>
