Hello all,

Moving it 30min early to 8:30am CDT works for Erik so there is a slot that works for everyone.

I will update the reminder emails.

Yours,
Roland

> Beyhan: In BBH gallery example, only two refinement levels why not three?. Zach: Two centres are enough.  Carpet merges the two refinement leves at the origin when the third BH appears so no need to include a third one. For BNS is better to have two ref levels that combine and form a big enclosing box to avoid matter fluxes in the refinement boundaries. Use trigger thorn to add more refinement levels when a BH forms.
