Hello Nisa Amir,
Thanks alott
Alright. Here is how to make it work. Please add these lines to your parameters file (kasner.par or kasner-med.par or kasner-hi.par):
# ML_BSSN ignores gauge evolution method parameters, so manually force its RHS # to be all zero ML_BSSN::harmonicF = 0. ML_BSSN::LapseAdvectionCoeff = 0. ML_BSSN::ShiftGammaCoeff = 0. ML_BSSN::ShiftAdvectionCoeff = 0.
somewhere after the other ML_BSSN settings in that file.
The lets me run and produces the correct answer, at least for gxx.
I will add more detailed information to the ticket I created:

Yours, Roland
