Hello all,

I need your help to solve the error in FLUENT.

I simulated heat transfer of thermoelectric module compiling UDF(using C++) in FLUENT 12.0 and 32bit windows XP.
(This simulation exists NO fluid.) This simulation was succeed.

After that, I simulated the simulation again using "same" boundary condition and setup in FLUENT 12.1 and 64bit windows XP, but error message occured without one calculation!

This error message said that " Divergence detected in AMG solver : temperature" , that can't be possible because both conditions are completely same !

Maybe this problems don't have root in my compiler.
I'm using Windows VS 2008 Express Version and SDK v7.0, and I started FLUENT from command prompt of SDK. Therefore, the compiler is recognized.

Of course, I desperately seeked FAQs about this problem and tried to reduce URF and change Advanced Solution control etc.
However, this error can't be solved.

Please tell me the solutions of this error or FAQs discribed solutions.

Thanks in advance.
