<div dir="ltr"><div><div>Dear Expert,<br><br></div>Here I attached two input files for hexagonal boron nitride (hBN) <b>hBN1_relax.in</b> and <b>hBN2_relax.in</b>. For <b>hBN1_relax.in</b> I'm getting the following error "<b>Error in routine sym_rho_init_shell (4): lone vector</b>" (output file is also attached below <b>hBN1_relax.out</b>) but for <b>hBN2_relax.in</b> in which I just reduced the lattice parameter and got no error at all. I don't have any idea, can anybody please tell me why this is happening ? And without reducing (or changing) the lattice parameter then how one can get rid of this error ?<br></div><div><div><div><div>Thanks in advance.</div><div><br></div><div><br></div><div><br></div><div>Regards,<br></div><div>-- <br><div class="gmail_signature"><div dir="ltr">Manoar Hossain<div>Research Scholar</div><div>School of Physical Sciences</div><div>NISER, Bhubaneswar</div><div>INDIA<br></div></div></div>
