Hello David,

This fnction has been deprecated for a very long time. It is not really likely to go away "soon", really.

The docs (https://einsteintoolkit.org/referencemanual/ReferenceManual.html#x1-33000A2) suggest using thorn CoordBase's APIs. Unfortunately its docs (https://einsteintoolkit.org/thornguide/CactusBase/CoordBase/documentation.ht...) do not really say what to use.

The function to use would be GetDomainSpecification, described in its interface.ccl file (https://bitbucket.org/cactuscode/cactusbase/src/921e6604ea87fa5a2773fa5ba864...):

CCTK_INT FUNCTION GetDomainSpecification \ (CCTK_INT IN size, \ CCTK_REAL OUT ARRAY physical_min, \ CCTK_REAL OUT ARRAY physical_max, \ CCTK_REAL OUT ARRAY interior_min, \ CCTK_REAL OUT ARRAY interior_max, \ CCTK_REAL OUT ARRAY exterior_min, \ CCTK_REAL OUT ARRAY exterior_max, \ CCTK_REAL OUT ARRAY spacing)

with the "obvious" arguments being passed to it ("size" is the dimension of the arrays and the arrays are arrays of CCTK_REAL).

Note that this will only work for Cartesian only simulations, and not for those using curvilinear coordinates provided by Llama (multipatch simulations).

Yours, Roland

Hello,

I just noticed that CCTK_CoordRange is depreciated and will be phased out soon. What should I use instead to find min/max values of coordinates? I could do reduction operations on the coordinate grid functions but that seems like a less elegant solution.
