Since no-one else has answered, I'll mention something that may be 
relevant. In 1986 we published a paper (DOI:10.1049/cae:19860050) that 
proposed a mesh-generation method that involved creating a structured 
tetrahedral mesh for the interior of an object and then generating an 
unstructured tetrahedral mesh to fill in between the object's and its 
structured core. The method was also described in a master's thesis 
(Boubez, 1987); a link to the thesis can be found at 
http://audilab.bme.mcgill.ca/~funnell/pub.html#theses .
