I'm solving a 2D CFD problem, which is generating a lot of co-located 2D velocity field data, using a regular rectangular grid. Some of the grid is masked out, representing ocean bottom topography. Is there a relatively simple way to modify ListPlotVectorField to ignore the masked out values (which are stored as as unphysically large values, but this is easily modified) Thanks.
