Re: [FEMM] Lua script to output B field and other info

["robert Macy" <macy@xxxxxxxxxxxxxx>]

Use lua to "map" B fields.  Use the lua script to calculate
a model, then use the "plot to file" function to generate a
table of values for B.  Always have to set the number of
points in the plot to something plus 1 to get even
positions.  for example, 51.  Also, plot both normal and
tangential to get the x,y directions.  For AC fields,
you'll get a complex value at each point.  

For multiple models, use lua to name the files in some
sequential manner, like Bn001, Bt001, Bn002,Bt002, etc.

Once you have text tables of data, you can do with it what
you need.  

Little more detail what you're doing and I can send sample
lua scripts.  But keep in mind I have the old version of
femm.  Where there were two step processing of lua.
