  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:
  Node 2: Process 23384: Received signal SIGSEGV.

  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.

    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.

  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.

    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.

  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.
