I have a .par file "Simple example of Schwarzschild using ADM". I need to simulate schwarzschild of a black hole but get the following error:

    ADMConstraints is no longer officially part of the EinsteinToolkit. It is still present in the einsteinanalysis repository however. If you would like to use that version, please add "EinsteinAnalsysis/ADMConstraints" to your ThornList file (Cactus/configs/YOURCONFIGNAME/ThornList then do make YOURCONFIGNAME if using Cactus or the thornlist THORNLISTFILE then do simfactory/bin/sim build sim --reconfig --thornlist THORNLISTFILE if using simfactory).

    You may have to first create a link from arrangements/EinsteinAnalysis/ADMConstraints to repos/einsteinanalysis/ADMConstraints:

    cd arrangements/EinsteinAnalysis
    ln -s ../../repos/einsteinalalysis/ADMConstraints ./
    

    Alternatively, you can use ML_ADMConstraints (does not require McLachlan despite its name) which is a more modern version of ADMConstraints.

    Your parfile seems to not contain any evolution thorn. If you only require a static metric you can also use ./repos/EinsteinExact/EinsteinExact_Test/test/KerrSchild.par which sets up the metric of a Kerr black hole (spin a = 0.8) in Kerr-Schild coordinates. Setting a to 0 would give you a Schwarzschild black hole.
