What would be the best way to extract the positions? I'm pretty certain that that would do it (the default value for START does not work because it just draws one streamline from the geometric center of the mesh!).

The top of my .general files looks something like this:

grid =   "N" x   "M"
field = VELOCITY, PRESSURE
interleaving = field
structure = 2-vector, scalar
type = float, float
series =            "NS"
majority =column
positions =   0.0E+00 ,   0.1E+00 ,   0.0E+00 ,   0.1E+0
0
end
  0.0000000E+00  0.0000000E+00  0.0000000E+00
{data to end snipped}
