Hey @sburger,
I think that the first column carries the z coordinates whereas the second column carries pressure values. This is because @rszoeke has chosen Z as the active parameter meaning that we primarily want the first column refering to the z-coordinates of our part.
Does this make sense to you?
Also see:

• How can we add a load depending on variables using SimScale?
and

If something is still not clear do not hesitate to ask.
Cheers,
