# ABAQUS: nice colorbar ranges

I have produced a python script that automates setting up reasonable values in the ABAQUS/CAE colorbar, basically setting up Tecplot functionality.  After executing the script from File->Run Script, you have access to a function that you can call in the built-in interpreter,

>>> SetContourRange(minval, maxval)

where minval and maxval are the min and max values that you want to be colored.  You can call this function as many times as you like after running the script.  There is an optional argument minIntervals (defaults to 10) that recommends to the function how many intervals you want between min and max.  It finds the nearest 1, 0.5, 0.25, or 0.2 (times the appropriate power of 10) that nicely splits the specified range, as shown in the example figure attached to this message.

I hereby release this into the public domain, but I request that you keep my name with the code (creative commons attribution-share alike).

If anyone spots any problems, let me know.
