Hi heat transfer in a tube heat exchanger (in 3D) have been modelised. in Fluent i define a thin wall BC (turn on the shell conduction option in the wall boundary condition panel, define the thikness, mterial). after some iterate. i want to display the temperature and the streamlines on the fluid and the wall but only the tempearture on the fluid i can seen

how display the streamlines in the wall Thank s

Well, how will you see streamlines "in" the wall when you cannot pass fluid through it?

i will see the isocontours of the temperature et not the streamlines in the wall , think you
