This is a fix for the global indexing mechanism in
MultiFab
that is needed in cases where the box array does not fully cover the domain. In those cases, the__getitem__
is done twice, once to get all of the data including places where the ghost cells internal to the domain cover places that are not covered by valid cells, and a second time to ensure that in places where the ghost cells do overlap valid cells, that the data used is from the valid cells.
