multiple results using makeplot

["alteredfrog <alteredfrog@xxxxxxxxx>" <alteredfrog@xxxxxxxxx>]

I am trying to right a bit of Lua code that will save the result from 
each step in a distinct file, or append the results to an existing 
file.

In the pre-processor script If I knew how I could incriment the file 
name before each "analyse()" call. This would save each solution set.

What may work better may be to pass the iteration step or file name 
value to the post-processor script and incriment or change the name 
of the file that the "makeplot()" data is saved to (graphical or data 
not to important which). Again I dont know how to do this.

I've only been working with the LUA script for 4 afternoons so its 
all still new. 

My goal is a "slide show" of the tangetial field along a selected arc 
as two parts move away from each other. 

thanks for the help in advance
