Hi, I am trying to generate an alternating e-field using gromcas input as following:
electric-field-x = 1.5 1 0 0 E0= 2 V/nm, omega = 1 cycle/ps This means a cosine wave of magnitude 1.5 eV/nm and 1 cycle per pico-second. I ran this input with mdrun -field option for a sanity check. I plotted field.xvg . Surprisingly, the plot (attached) is NOT showing 1 full cycle in a 1-ps period. It is only 1/4 cycle of a cosine wave. So, can you please point out what is that I am missing here?
