The way I would remedy the situation is: - look at the Mathematica source file for thorn ML_ADMQuantities - remove the declaration of the external ML_BSSN variables - peek at thorn ML_BSSN to find how these are defined in terms of the ADM variables, and insert this definition where needed, e.g. calculating det g from g_ij instead of from W
For someone familiar with Kranc that should be straightforward, and not more difficult than creating a second version that attaches itself to ML_CCZ4. -erik On Wed, Apr 4, 2018 at 8:53 AM, Erik Schnetter <schnet...@cct.lsu.edu> wrote: > As written, thorn ML_ADMQuantities requires another thorn with the > name ML_BSSN to be present. > > -erik > > On Wed, Apr 4, 2018 at 7:52 AM, Wolfgang Kastaun <phy...@fangwolg.de> wrote: >> >> >> On 04/04/2018 01:14 AM, Roland Haas wrote: >>> Hello Wolfgang, >>> >>>> @Roland: In the interface.ccl of ML_ADMConstraints I only see the ADM >>>> constraints, no expressions for ADM energy and angular momentum.
