Hello Jason,

you might look at the file
#p"femlisp:src;application;domains;inlay-domain.lisp" (especially the
functions n-cell-with-cubic-inlay and n-cube-with-ball-inlay) Maybe this
does already something similar to what you want. (Those domains are used in
the homogenization demos where effective properties are computed.)
Otherwise you should describe your situation more precisely.

If you have irregular domains, then Triangle will probably be necessary.
Please check, that the program is installed correctly with 'make triangle'.
(Probably you will have to change the file
#p"femlisp:src;external;triangle/makefile" to compile without the -DLINUX
