sampathevs is on a distinguished road

Can Anyone help me in writing a UDF for an temperature dependent expression ?

The eq. is .

A = 0.9 * exp(-5Tff) - 0.5 and here.

Tff = 373+ 0.5(Tinlet - Toutlet)

Here T inlet, is the temperature I define in inlet boundary condition and T outlet will be calculated by CFD automatically with energy equation.
