<div dir="ltr">Dear users,<div><br></div><div><div>I want to calculate ionization potential (IP) and electron affinity (EA) for a 2D material (periodic), for this I have set <b>tot_charge=+1</b> & <b>tot_cahrge=-1</b> but I need background correction due to this extra "+1" or "-1" charge in the system. To do so I have set <b>assume_isolated="esm"</b> and <b>esm_bc="bc1"</b>. Does this serve the purpose ?</div><div>If not then what should I do ?</div><div><br></div><div>Even for above case I'm getting an error which is </div><div><div><b>Error in routine esm_cft_1z_init (1):</b></div><div><b> no scalar fft driver specified</b></div></div><div><br></div><div>Any suggestion will be appreciated. </div><div><br></div><div><br></div><div><br></div><div><br></div><div>Thanks and Regards,</div>-- </div><div><div class="gmail_signature"><div dir="ltr">Manoar Hossain<div>Research Scholar</div><div>School of Physical Sciences</div><div>NISER, Bhubaneswar</div></div></div>
