McLachlan sets r->infty values of metric incorrectly

Issue #2016 new
Roland Haas created an issue

The (not usually used) "radiative" boundary condition uses the gt11_bound_limit etc to specify the limit of the fields at large radii. However right now the defaults for gt11, gt22, gt33 are all zero which is rather useless. I know that default values are not "sensible" values but rather "historical" values, but I question at which point in time it made sense to have the diagonal elements of the metric that we assume to become Minkowsky (since phi->0) would tend to zero.

    As far as I know, the radiative boundary condition in McLachlan's master branch is nonsense, unless Erik fixed it during the rewrite. There is a version in the cakernel branch which is correct, and has been tested against NewRad. A pure-Kranc version was needed for working with CUDA/OpenCL.
