[Nek5000-users] Adjacent vertices / cells

[nek5000-users at lists.mcs.anl.gov]

Hi all,


I'm just wondering if there's a way (given a particular velocity cell's local (i,j,k,e) co-ordinates within the domain) to access the 6 adjacent cells - even if they are located inside a different element.


If so, how does this deal with cells on the boundary, where there may exist fewer than 6 adjacent cells.


Many thanks,


Lee
