I am currently working on validation of a small project and it includes flow conditions in parabolic profile and temperature conditions varying in a linear fashion increasing along the Y axis.

Velocity varies as
u(y)=12(y-(y^2)) and y ranges from -1/6 to 1/2

Temperature varies as
θ(y)=(1-2y) and again y ranges from-1/6 to 1/2

My main problem is i don't understand how to define the centre-line velocity i.e maximum velocity and temperature conditions. Also from a previous experience, I couldn't include two different UDF's for different boudary conditions. Is it possible to write both the UDF's in a single program

I have included all the required data probably. In case anything else is required, I would respond. Please help me out.
