<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I tried to optimize the molecular
structure in a saw-like electric field using espresso-3.2. However, the
optimization is always failed. I checked the forces through the numerical
method. It seems that the forces in a electic field are wrong. Maybe the version
I used is old. Does anybody have the same problem? </FONT></DIV>
