AmrLevel::Derive() generates bad data

maxpkatz opened this issue · comments

When using a certain combination of boxes, e.g. inputs.128 with amr.max_grid_size=32, the diagnostics report NaN's. This occurs because the calls to derive that are being used to fill in the fields for the diagnostics are generating bad data with NaN's in them, which implies some problem in FillPatch.
