I have changed parameter as per your suggestion given in the frequently asked question. So i modified RMT value, Lmax , E parameter and also i also redued the RMT initially in the force minimization upto 5%. but still i am facing the same problem during the scf run. I have modified the case,in1c file upto this lebel. <br></div><div><br>WFFIL EF= 0.50000 (WFFIL, WFPRI, ENFIL, SUPWF)<br> 6.00 14 4 (R-MT*K-MAX; MAX L IN WF, V-NMT<br> 3.0 4 0 (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global APW<br><br></div><div>So please tell me about what is the maximum and minimum criteria of these RMT value, Lmax , E parameter and also tell me about how these parameters will effect the ground state properties. <br></div><div><br><br><br><br><br>Thanks<br></div><div><div><br><div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><b style="background-color:rgb(255,255,255)"><font color="#0000ff">Goutam Kumar Gupta</font></b><div><div><b style="background-color:rgb(255,255,255)"><font color="#0000ff">Mob:8561995547</font></b></div></div></div></div>
