tahtawy is on a distinguished road
In a transient analysis
I want to define Q_loss from tank walls to ambient as a function of
1- The average temp of the tank ( varied with each time step )
2- Temp of the surrounding (varied with each time step )

This will be used as a boundary condition for the tank wall

Q_loss=1.2*(T_av_tank - T_surr)^1.26

If any one please can make udf function for that as i don't know how to make it or if there any other easier way to incorporate this as boundary condition of the tank wall?????
