Dear all,
I am trying to model a wall with an active layer in type 56_a, however every time i use an input in the user defined convective heat transfer coefficient of wall, i get a wrong results of the surface temperature as TRNSYS prints out the ambient temperature instead of the surface temperature. if i use constant value instead of an input this problem disappears. any idea how can I solve this problem.
your help is highly appreciated,
Thanks
Ahmed
