Dan,
Sorry I was being forgetful. The specific item was from
another mail-list, FEA-L. Here is the message for you.

There is a fairly easy way to get an all hex mesh in an arbitrary volume
within ANSYS. The ANSYS mesher can put all hex element into a tet volume.
To get a hex mesh first mesh the volume with tet elements, then use a macro
to convert the tet elements into tet volumes, then mesh the tet volumes
with hex elements. Some of the corner angles may be ugly but if want/need
all hex elements this may be an option.
