Yes, just to second Brad's comment...  Continuously variable  
properties based on element centroid location are no problem in  
principle, but in practice require writing new code (and validating/ 
debugging it).  The best short-term solution is to have a modest but  
reasonable number of material classes that map to the realistic model.

in practice, there's a difference."
