<div>Dear CP2K developers,</div><div><br /></div><div>I was wondering whether it exists a simple method in CP2K (v. 2025.1) </div><div>to constraint the maximum value assumed by O-H covalent bonds (let say</div><div>at 1.3 Angstrom) in ab initio molecular dynamics simulations of bulk liquid </div><div>water without specifying a single COLVAR for each O-H covalent bond distance,</div><div>a not practical circumstance implying defining 2*N COLVARS and 2*N CONSTRAINTS. <br /></div><div><br /></div><div>Many thanks in advance and best wishes,</div><div>Giuseppe <br /></div>
<p></p>
