Hello all,
there is, as far as I remember, not having looked at their code at all, ML_ADMConstraints that computes the constraints based on the ADM variables (even though it is in the ML repo). Not sure if there are grid functions that match what you are looking for though.
Yours, Roland
Wolfgang
I don't think such a thing exists.
It should be relatively straightforward to calculated the ADM quantities from the ADM variables. I also think this is how it should be done; I was surprised to see that it is done differently. After all, that's why we have the ADM variables -- as lingua franca so that thorns don't have too many interdependencies.
Do you need the ADM integrands everywhere or just on a 2-sphere? If the latter, then the thorn QuasiLocalMeasures could provide these.

Hi,
I just started using the ML_ADMQuantities thorn (because I wanted the ADM integrants, not just the integrals), and stumbled on two issues:
- It seems this thorn only works with ML_BSSN, is there a version
for ML_CCZ4 somewhere?
- Madm and Jadm3 are declared as tensorweight=0 in the
interface.ccl, but it seems to me that they already include the square root of the 3-metric determinant (at least I got the correct ADM mass by just using the standard average reduction operator on them for some test). Should that be tensorweight=1 instead?
Cheers, Wolfgang.
