# These are (almost) copies our grid functions.
# They contain T_munu, the stress energy tensor, excluding the contributions
# that other thorns add via the CalcTmunu.inc mechanism.
# That is, this copy includes only the contributions from the AddToTmunu
# mechanism.

# This copy is protected, so that it is pushed into ADMCoupling's list of
# grid functions, so that other thorns can access it implicitly via the
# CalcTmunu.inc mechanism.
