temperature dependent heating on an interface

[aminer2k]

Hello,
In Ansys V9, I am trying to model interface heating on an interface between two material domains, with the amount of heating at the interface being temperature dependent. This is a steady, 3d thermal analysis. I can apply the interface heating to the area, or to the nodes at the interface using the function editor to create a table. The interface heating works fine when I make it a function of x,y, or z, but as soon as I use a function for the interface heating that is a function of temperature, the function is ignored by ansys. The table that the function editor generates is correct, but the simulation ignores the heating when temperature is used. How can I do a thermal analysis with interface heating being temperature dependent? Is tabular boundary conditions created by the function editor the right approach?

Hi,
I basically can find a reason why it doesn't work: you are linking a dependent variable (heat gen) to another dependent variable (temperature), i.e. an input variable is dependent upon an output variable. So it is impossible for the program to set up the initial value for the variable "heat".
The way out substancially depends only upon your particular case. Probably you can build an APDL in order to do iterated solves, starting from a "first-try" temperature.
Hope this helps...
