what is the meaning of regrid(0, time) in the AmrCoreAdv::timeStepNoSubcycling routine.

[ztdepztdep]

I do not understand why it only regrid level 0 grid in this call no matter the maxlevel i have set.

`// Advance all the levels with the same dt
void
AmrCoreAdv::timeStepNoSubcycling (Real time, int iteration)
{
    if (max_level > 0 && regrid_int > 0)  // We may need to regrid
    {
        if (istep[0] % regrid_int == 0)
        {
            regrid(0, time);
        }
    }
}`

That call is not regrudfing level 0 - it is regridding all levels > 0. 0 is the base level Ann Almgren Senior Scientist; Dept. Head, Applied Mathematics Pronouns: she/her/hers
