The charge convergence is very sensitive to
numerical issues, so using -cc 0.0001 demands a lot and is probably not a
good idea"<br><pre><br></pre><pre>I ran calculation via w2web and also with terminal with -cc 0.0001 (suggested in UG) or -ec 0.0001.<br></pre><pre>It conversed again in 14 cycles.<br><br></pre><pre>Any comment why it is not conversing at 11 iterations?
