[Nek5000-users] Mesh issue

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

Hi Hugo,

What are the boundary conditions on your box?

Is there a reason not to simply tilt the box and realize
the incline in this manner?

Boundary conditions invariably have 3 characters in Nek.
I don't know which converter you are using, but "   " as
a bc would translate either to "E  " if it's an interior
element boundary, or to something unknown otherwise.

Best regards,

Paul
