Im interested in cube sphere topology. the reason is i would like to code up a solver off-line on a cube-sphere grid — the intention is for it to eventually enable STREAMICE to run in a cube-sphere grid in order to be coupled with AIM.</div>

i read the page <a href="https://mitgcm.readthedocs.io/en/latest/phys_pkgs/exch2.html" id="LPlnk997989" class="OWAAutoLink">
https://mitgcm.readthedocs.io/en/latest/phys_pkgs/exch2.html</a> and didn't find that it answered my questions that i could see, at least not directly enough! however, i ran the solid-body.cs-32x32x1 verification and looked in the file w2_tile_topology.0000.log
that are produced, and it might be closer to what i was looking for, but i would like to make sure i understand:</div>
