hi all,
i was wondering whether there is a way to add inner refinement levels with CarpetRegrid2 (or CarpetRegrid) as a simulation progresses. let's say that i have some configuration that collapses to a black hole, and i want to keep resolving accurately the inner region. is there some way for me to tell CarpetRegrid to add inner levels whenever a certain condition is fulfilled, ie, enough time elapses, or some grid quantity (like the lapse) grows beyond a certain value?
thanks, Miguel

The easiest way is likely to use the Triggers thorn (in CactusUtils/Triggers). See http://einsteintoolkit.org/gallery/bns/nsnstohmns.par in http://einsteintoolkit.org/gallery/bns/index.html for an example when simulating neutron stars.

hi Roland,
this seems to do what i was looking for. i'll try it out and report back if i encounter any difficulties.
thanks! Miguel

Hello Miguel,
no problem. I notice that I mispelled the thorn name though "Trigger" and not "Triggers" is the correct name.
Yours, Roland
