<div>Hi,</div>I did a run with <div> TmunuBase::support_old_CalcTmunu_mechanism = yes </div><div>and it works. However at the beginning several iterations i got 'poison values' after the values ok. Another thing is that Surface Integrals Values osculate from 0 to correct value for the ADM mass. Volume Integrated ADM Mass looks ok. </div>

</div>Hi,<br>
<br>
Do values 'look ok' every so and so iterations? If so, something is<br>
likely to be wrong with past time levels. ADMMass performs reductions,<br>
which use time interpolations in case refinement levels don't line up in<br>
time. If past timelevels are not populated correctly this would show as<br>
strange numbers. Every so many iterations (depending on your setup)<br>
however, all refinement levels are 'at the same time'. Then no time<br>
interpolations are done and values should be ok.<br>
<br>
Another possibility is that because ADMMass uses ADMMacros and ADMMacros<br>
use the old Tmunu mechanism, this can go wrong when you do not use<br>
TmunuBase::support_old_CalcTmunu_mechanism = yes (not advised in<br>
general: slow!)<br>
However, I would not expect numbers _that_ wrong in this case. However,<br>
I would like to know if this should indeed be the problem.<br>
