Hi,

I´m tryin to model natural gas saturated with water, using a mixer and a separator, and then adjusting mass flow rate until vapor fraction is 1.0, however I'm not getting it to start solving since it shows the following error:

"water: index was outside the bounds of the array"

What does that mean? What am I doing wrong, since this should be a fair simple model.

Attached is the file.

Thank you in advance!
