Default ill posed problems: inverse heat transfer

Hi everybody !

Can Fluent solve ill posed problems. I mean inverse heat transfer problem. i.e if I know what is the temperature of certain locations inside my domain (not on the surface) by inserting thermocouple and monitoring temperature with time. Can I use this data and calculate the heat transfer coefficient at the boundarys.

Hope I have made myself clear. If anyone has used fluent to do this please let me know how.

Thanks in advance

Rajeev

It could be possible if Fluent allows BC on nodes using UDFs. Read manual whether Temperature can be applied as BC on nodes!

Unfortunatly you can't do that with fluent.

This problem is an inverse problem and can only be handle by an inverse code. As far as I know inverse methods in cfd are still under development due to the strong non linearity of the NS equation.

I think that this problem have allready be debated in cfd online and that you will find more information by searching the database.

hi all, i have a square with heat generation rate inside that, i have three boundary conditions with constant temperature, but i dont have heat flux from one of walls, i want to simulate this problem in Fluent, could you please any one explain me??
