#2639: CarpetLib internal error with PreSync and analysis thorns

 Reporter: Samuel Cupp
   Status: new
Milestone: 
  Version: development version
     Type: bug
 Priority: major
Component: Carpet

Comment (by Samuel Cupp):

So, the heart of the problem comes from \(I think\) the function

```
th::regrid()
```

in repos/carpet/CarpetLib/src/th.cc:51. When this runs, it sets the

```
deltas.AT(ml).AT(rl)
```

object to 1.0 \(possibly divided by the timereffacts\), which then causes an incorrect cctk\_time. This seems to be polluting some functions which call get\_time. This happens without PreSync, but by miracle \(design?\) it gets reset to the right value before anything tries to use it. This does not occur in time with PreSync.
