hi Erik,
i've attached a simple parameter file that shows the problem. if i comment out
the line
Carpet::prolongation_order_space = 5
it seems to go through.
thanks,
Miguel

Yes, Carpet prolongates with the same order in each direction. However, in your case, prolongation
in the z direction is exact and does not require any ghost zones, since nothing needs to happen in
the z direction. Carpet should handle this correctly. Can you post a complete, simplified parameter
file to reproduce the problem?

hi all,
many thanks for the parameter file, Steve. it works, but as soon as i set
Carpet::prolongation_order_space = 5, i get inconsistent grid structure
type of errors:

int Carpet::Abort(const cGH*, int): Assertion `0' failed.
so i guess it's as Ian said, that Carpet tries to prolongate with the same
order in every direction?
i find that in order for this to work i either have to decrease the
prolongation to order 1, or put
the boundary along the z direction back to a non-zero value. but i guess in
this latter case i no
longer have a truly 2D configuration, right?
thanks,
Miguel
