Currently it is possible for the user to add too much negative displacement in seismic mode, resulting in a net offset of the seismometer and the displacement field. I added some dispersion to the wave equation to deal with this problem, but no longer remember why. We should

  1. Figure out why I did that.
  2. Figure out if there is a better way to handle net offsets.
