[yt-users] covering grids, memory

[Matthew Turk]

Hi Dave,

It is, but it's a bit DIY and will require incompatible changes that
then require recompilation.  The covering grid machinery is written in
C, usign the Python/C API.  So you have to modify the initialization
of the empty (zero) grids in Python code in
yt/data_objects/data_containers.py, and then again in
yt/utilites/data_point_utilities.c in the FillRegion section.

It might be easier to do it piecewise over the domain and then
down-convert manually.
