[Nek5000-users] Parameters lx3, ly3 and lz3

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

Hi Tony,

Most often I take lx3=lx1.

I have had occasions where lx3=lx2 was required -- e.g., a tapered cylinder flow
using Pn-Pn-2 (lx2=lx1-2).

lx3 governs the degree of polynomial for the geometry.

Best,

Paul

Dear Neks,

Does anyone have any clue on the lx3, ly3 and lz3 set-ups below?

Best,
Tony

Dear Neks,


I've got a quick question about the parameters lx3, ly3 and lz3. These are the parameters for mesh3, but I'm not sure how they work in the code. For velocity and pressure, I would assume we only use mesh1 and mesh2. I'm just wondering is it necessary to set lx3 to be equal to lx1 (if I'm using PnPn-2)? Or does it matter whether it is equal to lx1 or lx2?


Hope anyone could help with this. Thank you very much in advance.


Best regards,

Tony
