prolongation='none' is one of the possibilities; there are other prolongation types, e.g. sync, restrict, or copy.
To find out what is going on, we need to find out which thorn called on Carpet to interpolate in time for what reason. A stack backtrace or similar information would be useful.

Here is the backtrace

I haven't declared it with prolongation=none, but I never interpolate it, reduce it, or sync it. How do you declare this variable? You may need to explicitly tell Carpet to leave this variable alone, or to report an error when such an operation is attempted. How do I do this? -erik On Mon, Dec 12, 2011 at 11:35 AM, Frank Loeffler <knarf@cct.lsu.edu <mailto:knarf@cct.lsu.edu> <mailto:knarf@cct.lsu.edu <mailto:knarf@cct.lsu.edu>>> wrote: On Mon, Dec 12, 2011 at 10:32:55AM -0500, Yosef Zlochower wrote: > -> Internal error: extrapolation in time. variable=LAZEV::dotalp > time=118.90625 times=[118.9375] > > I am unsure how the times could have gotten out of sync at such a late > time in the simulation without getting out of sync earlier.

It might happen that in order to regrid at that particular time Carpet would need to interpolate in time, and it didn't do before because levels might have been lined up at the time of regridding.
