[Users] shrinking of computational domain at recovery

[Kentaro Takami]

Hi, Ian,

> As far as I know this is not possible using checkpoint/recovery.  You might be able to use the "file reader" mechanism to make CarpetIOHDF5 read data from the checkpoint files as new "initial" data, and in that case, I think the grid does not have to be identical, though the points have to line up (there is no interpolation).  I'm not sure how to use this method -- maybe someone else can help with that.


Thank you for your suggestion.

Finally I could do this by CarpetIOHDF5 reader.
Exactly speaking, we can use not checkpoint files
but HDF5 3D data files with only a iteration slice,
because reading checkpoint files derive unexpected behavior.
