>= 20.1 to CarpetRegrid2::radius_1[5] = 25. I tried to do that by making <br>

<br>
if nothing changed, making the parameter steerable is the problem. It is <br>
not steerable, because the thorn CarpetRegrid2 only ever looks at the <br>
parameter at the beginning. You can make it steerable, but it won't do <br>
anything to your simulation, as you observe.<br>
<br>
What you can do instead, is to change one of the variables (not <br>
parameters) that Carpetregrid2 uses, e.g. (not adapted to your case, but <br>
that should be similar):<br>
<br>
Trigger::Trigger_Checked_Variable[2]="ADMBase::alp"<br>
Trigger::Trigger_Reduction [2]="minimum"<br>
Trigger::Trigger_Relation [2]="<"<br>
Trigger::Trigger_Checked_Value [2]=0.1<br>
Trigger::Trigger_Reaction [2]="steerscalar"<br>
Trigger::Trigger_Steered_Scalar [2] = "CarpetRegrid2::radius[2]"<br>
Trigger::Trigger_Steered_Scalar_Index[2] = 4<br>
Trigger::Trigger_Steered_Scalar_Value[2] = "3.75"<br>
