The problem is: x/length is not dimensionless which is quite strange.

If it's written in this way:

'
length = 0.0033 [m]
ratio = x/length []
heat transfer coefficient...

Hi

I'd like to define a position dependent variable by:

'
length = 0.0033 [m]
heat transfer coefficient = 0.1-x*(0.1-0.07)/length [m s^-1]
'
.
