The xansys netiquette asks that you give your name and affiliation. If you
are not getting any answers to your question, try reposting with the
aforementioned information. And think long and hard about asking too many
homework questions of this group. I personally don't mind giving a little
homework advice but there are some codgers on this list who will rip you a
new one.

Hello:
I'm trying to make a transint thermal analysis of a pipe.
The pipe is a the begining at -20C and the a fluid flows in the
inside with h=500 and t Fluid=60.
The outside of the pipe is insulated
The model is 3D using solid 90.
For some reason the head is not conducted from 1 element to the next.
