Hi Joe-

Are you trying to plot all timesteps? Are these staggered grids, or
on regular coordinates.  The staggered grids use more memory.  What
vertical coordinate are you using?  The WRF Eta coordinate also
uses much more memory.

We will be working on ways to reduce the memory consumption by the
IDV for the next release.  Unfortunately, for now, my only suggestion
is to subset on time.
