<DIV>Dear Lorenzo Paulatto</DIV>
<DIV> I am very sorry for my last letter .I don't know why it become some garbage, now I send it again .</DIV>
<DIV> </DIV>
<DIV> I only want to add a homogeneous finite electric field .In the instruction of the dipfield paremeter ,it said dipfield turn on only tefield is turn .So I don't know why you introduce the usage of parameter dipfield ? <BR> I have see the code of forces_bp_efield.f90 in version 4.1(my cluster installed) .It seems that :"PAY ATTENTION:EL FIELD AND OCCUPATIONS" is not a error .My question is why when I turn on the lefield ,relax is so slower than without adding efield ? And one puzzled problem is ,at the start ,when the first iteration has not achieved the save file has turn up .<BR> <BR></DIV>
<DIV>
<DIV>Best regards</DIV>
