<div style="font-size: 16px; font-family: Tahoma; color: rgb(0, 0, 0); font-weight: 400; font-style: normal;">Hi Everybody.</div>
<div style="font-size: 16px; font-family: Tahoma; color: rgb(0, 0, 0); font-weight: 400; font-style: normal;">Is it possible I define my own constraint and thereby the relevant penalty functional for the pwscf calculations or constraints are limited to the ones listed in DOC?</div>
