[Nek5000-users] Issue in 3D NEKNEK simulations

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

Hi Sudhakar,

Thank you for sharing your experiences with using NekNek. We have run many
3D examples with it, and it has been working fine. Maybe, you can send your
modification to an eddy_neknek case where you experience this problem
offline, and we can look at it?

Best regards,
Yulia Peet
