[Nek5000-users] visit: looking at velocity components when using the .vtk-format

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

Hi Johan,

VisIt shouldn't do this ... I don't know what's going wrong, but if
there is vector data in the file, VisIt should preserve it.

Can you get in touch with me at hchilds at lbl.gov and get me the VTK
file?  I'll take a look.

Best,
Hank
