’interpolated’ in ph.in will do it as I know.</p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;"> </p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;">But I can't find how I can set the specific the number of dense q-grids.</p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;"><span style="font-size: 14.6667px; line-height: 17.6px; font-family: 돋움; margin-top: 0px; margin-bottom: 0px;"><br></span></p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;"><span style="font-size: 14.6667px; line-height: 17.6px; font-family: 돋움; margin-top: 0px; margin-bottom: 0px;">Is there any tag in ph.in to adjust interpolated q-girds? or Is scf.fit.in file related to dense q-grids?</span></p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;"> </p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;">Thanks.</p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;"> </p><p style="font-family: 돋움; font-size: 14.6667px; line-height: 17.6px; margin-top: 0px; margin-bottom: 0px;">Best regards,</p>
