[Users] Carpet 3d output

Hi all,

I made the observation that Carpet's output is quite large compared to the grid structure:

on 100^3 gridpoints per refinement level dumping admbase::metric (6 gridfunctions) in 3d hdf5

I would expect for 1 ref-level 10^6*6*8b = 48Mb. I got 80Mb. I assume that is because Carpet also includes x, y, z, and t in the dump, which brings it to 10 GF's and 80Mb expected.

But for 2 levels I got 250Mb. For 3 levels I got 450Mb and for 4 levels I got 620Mb.

This seems much even if I take ghost- and buffer-zones into account.

Am I missing something, or is Carpet doing something unexpected?

thank you

Michael
