<div dir="ltr"><div>Dear users,</div><div>I want to compute MSD of CaO using QHA module
for expanded lattice constant =10.2174 a.u (9.1334 a.u being
equlilibrium lattice constant). But I face some error and my MSD is not
generated. Attached file has force constant and the error faced during
calculation. <br></div><div>Any kind of help to solve the error is appreciated.</div><div>Thanks and regards.</div></div>
