[Nek5000-users] Symetric / Antisymetric boundary conditions

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

Hi Nek's,

I am currently investigation the linear stability of a symetric base flow
using the linearized perturbation mode. As a matter of fact, I meshed only
half the domain and used the appropriate symetry boundary conditions. Up to
now, I was intesrested only in its stability with respect to symetric
perturbations and thus had no problem. However, I am now interested in its
stability with respect to antisymetric perturbation and I was wondering if
there is any relatively simple way to implement such condition?


Regards,
