[Nek5000-users] Adjacent vertices / cells

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

Hi Paul,


Thankyou very much for your prompt response,


I'm tracking an immersed object within the fluid. I can determine whether a velocity point is within the boundary using face normals and dot-products, but I need to know whether it is connected to an outside-boundary cell.


Cheers,


Lee

Hi Lee,

The SEM is more function-based than cell based.

My guess is that Nek might alread support the higher-level
 operation you are trying to implement.  What is your
objective?

Best, Paul

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
