Hello everyone,

I am working with Fluent (ANSYS) and I have the following work to do : I must use a UDF to work on reduced kinetics schemes. For that I use a DEFINE_NET_REACTION_RATE subroutine. But in this subroutine, I have to call a fortran subroutine that contains the code for reducing my chemical mechanism. My problem is :
When compiling everything, no problem , when running Fluent on a case with the UDF, no problem. But my flame is estinguishing. So I would like to know if really Fluent uses the fortran subroutine. How could I do to know it? Do someone have worked with reduced mechanisms? I've been trying for months without any solution. If someone is ok for at least, "thinking " of it, I could send my files (fortran and C files). I don't know if my problem is in programming (problems with variable declarations...) or in the contents of the program itself.
Thank you for any help !!!
