update gauge settings in TOV example to be more typical
Issue #2520
new
The current gauge setting in the TOV example match what was used in the ET paper so that one produces the same plot. However that choice is somewhat unusual:
ML_BSSN::harmonicN = 1 # these set:
ML_BSSN::harmonicF = 1.0 # dot[alpha] = - alpha A
ML_BSSN::evolveA = 1 # dot[A] = dot[trK]
ML_BSSN::evolveB = 1 # these set: dot[beta] = dot[dot[beta]] = 0
ML_BSSN::ShiftGammaCoeff = 0.0 # by choosing coeffs to zero the RHS
ML_BSSN::AlphaDriver = 0.0
ML_BSSN::BetaDriver = 0.0
ML_BSSN::advectLapse = 0
ML_BSSN::advectShift = 0
and it may make more sense to use settings that are closer to BNS setup so that they can be generalized eg:
ML_BSSN::harmonicN = 1 # 1+log
ML_BSSN::harmonicF = 2.0 # 1+log
ML_BSSN::ShiftGammaCoeff = 0.75
ML_BSSN::AlphaDriver = 0.0
ML_BSSN::BetaDriver = 1.0
ML_BSSN::LapseAdvectionCoeff = 1.0
ML_BSSN::ShiftAdvectionCoeff = 1.0

@Roland Haas I was going through milestone tickets and saw this one. Is this resolved?

reporter As of 2024_05 “Lev Landau” those settings are still the unusual ones.
