Hello Steve,
using Carpet's cell centered refinement you should enable the
CarpetLib parameter:
CarpetLib::use_higher_order_restriction = "yes"
and possibly increase the default value of
CarpetLib::restriction_order_space
from its default value of 3. Note that values larger than 3 can be
Hello Arshad,
you will need to have the subversion version control system installed.
Given that OSX has a built in subversion client (so the exact message
that you see if not shown) I am assuming that you are using a version
of GNU/Linux (either natively or as Windows 10's Linux subsystem).

Ok. Since it starts with at "_" I almost suspected it may be some
Fortran binding but
Hello Bernard,
I am still in the process of trying to reproduce your error.
However one thing I noticed is that (yet again) Cactus needs a new
architecture file (once for each Apple update) and reports that darwin
18.6.0 is not a known architecture. This may be part of the reason for
failure.
Hello Cole,
While I still do now have a reproduced my original plot of the
collapsing NS that was in in the ET paper, if you issue is that the
fluid speed exceeds the speed of light, you may see a benefit in setting
GRHydro::reconstruct_Wv = "yes"
Yours,

I see. I had no idea that this is what the grid function does.

Hello Miguel,
assuming that your outer boundary is spherical, your should set:
NewRad::z_is_radial = "yes"

Hello Xiaoxiao,
I am not sure if CarpetAdaptiveRegrid is still the way to go.
The most recent use of adaptive mesh refinement is the AMRToy thorn
that you can find in the Carpet repository.
That thorn uses the "level_mask" grid function of CarpetRegrid2.
Basically at each point on the grid you
