Hi,

I am to run a simulation with Carpet in "ungrid" mode, that is, without
mesh refinement. I don't seem to get it right. What's options do I need
to set? Apart from setting Carpet::max_refinement_levels = 1, what else
does one have to specify in orer to get a run with only one grid?

Hi Dumsani,

What goes wrong? Do you get an error message? You don't even have to set max_refinement_levels to 1; you just have to make sure you don't ask for any more than 1 refinement level from CarpetRegrid2.
