How can a funtion be applied in a boundary expression?

I want to apply following step function in my temperature boundary condition:
T= 300+beta+t t<50
T=450 t>=50

How can this be applied?

for example

T= (300+beta+t)*(t<50)+450*( t>=50)

Better is to define a function in the "Definitions" section, piecewise is an option.
I recommend using a smooth step function.
