[Nek5000-users] Question about method & error

Hi Frank,

We dump the data using the GLL points. For visualization there is also an option to dump the data on a regular (uniform) mesh.

> Also, are the passive scalars stored at the PN nodes?

Yes on the GLL nodes.

> In the PN/PN method, is some filtering done to remove the spurious modes

No, there is no filtering needed because the method is free of spurious modes.

> By the way, are you in Europe?

Yes, but I'll move to the US soon.
