Is that a _python_ calculator expression or a normal calculator filter
expression?
It looks like the normal calculator to me and it may well be that you
can not create two component arrays with it. Additionally, it doesn't
have a way to mark the array as the active scalars. Just assigning the
name won't do it.
I recommend using the python filter instead and then calling
point_data.SetTCoords("nameofyourarray") instead.
good luck!
