[Nek5000-users] Number of elements for 3D simulations

Hi David,

You're refering to periodic, correct?

Is your spanwise direction the "z" direction in the element? (really,
what we call "t"...)

We might be able to correct the issue for this particular case,
assuming you don't have periodicity in the other directions.

Paul
