Dear all:<br><br>After I read the paper, "Picosecond Melting of Ice by an Infrared Laser Pulse: A Simulation Study" (Carl Caleman and David van der Spoel, Angew. Chem. Int. Ed., 2008, 47, 1417-1420), I decided to implement a time-dependent electric field on my simulation system. But when I read the gromacs manual I found it hasn't been implemented in gromacs yet. So may I ask is it possible to apply a pulsed, time-dependent electric field in the newest version of gromacs?<br>
<br>Thank you!<br><br>Fangyong<br>
