Thank you Amine for reply,

I am finding difficulty in writing the UDF for above mention breakage and coalescence models. Because these models have integration/double integration in their formulation. In few research article, they have solve that integration by incomplete gamma function. Again how to express incomplete gamma function in fluent is not known to me. If you know the way how to write that, it will be great help. I am attaching a research article where this integration is solved by incomplete gamma function.

You can read CFX manual and try to incorporate both kernels into Fluent. Again we do not download attachments.
