<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;mso-fareast-language:EN-US">The force field is not properly defined in your input, e.g. a SHELL_CHARGE is set but no CORE_CHARGE. It is difficult to check the other parameters, because you did
not specify the force field parameters for CeO2 which you want to use. The &CHARGE sections for rigid ion potentials should not appear when you specify &SHELL sections for a core-shell model. There is also no need to specify initially in addition to the &COORD
section a &SHELL_COORD and a &CORE_COORD section. The &KIND sections can be dropped, because these are not considered by the Fist module. I am also not sure, if the lattice vectors and the atomic coordinates are matching and thus will represent the fluorite
structure of CeO2 with PBC properly.<o:p></o:p></span></p>

so accurate or not suitble for cp2k. So how could I deal with this problem? Please find one of my inputs in the attachment.<o:p></o:p></span></p>
