I think that
a[:] = b * c
should make "a.value" an actual array. Also you can always get the
array value by simply forcing with "numpy.array(b * c)", which
removing any vestiges of FiPy from the object.
There may be a good reason to make the assignment, but it might also
indicate that there is a better way.
