Using the DEFINE_HEAT_FLUX udf, I get errors when interpreting, and when compiling I am not able to apply the udf.  But when I interpret after compiling, I am able to apply it, but i get this error when running:

The fl process could not be started.

Can anybody help?

If it fails to compile there's a problem with the code. The interpreter isn't as rigorous and doesn't permit all macros so isn't used as much now. 

[jmsz7x]

Hi rob.  Let me clarify, it doesn't fail to compile, I just am not able to apply the boundary condition.  I can compile and load the library with no errors. 

[Rob]

It's not a boundary condition, it's an adjustment to how Fluent applies the heat flux. The boundary condition is applied on the boundary, DEFINE_HEAT_FLUX isn't, and is covered in the manual. 

[jmsz7x]

The manual does not mention much at all about the use of the macro.  As I mentioned in the initial post, I was able to apply it as a boundary condition, but I am getting errors.

[Rob]

Other than it's not a boundary condition, and to use DEFINE_PROFILE for bc setting. The error is a consequence of DEFINE_HEAT_FLUX not being a boundary condition.

Thank you
