Boiling and Condensation (Phase Change) UDF
Hi all,

I'm new to ANSYS fluent, but I need to write udf for phase change including boiling and condensation in VOF model (which I think is a very difficult task for a newcomer like me). I had read through ANSYS UDF guide for some brief ideas. The following is what I think I need to write in the UDF after those readings (correct me if i'm wrong):

1. Define source terms in both liquid and vapor phases;
2. Define the mass transfer macro(where phase changes occur).

Is this correct? If I'm wrong what should I focus on? Any suggestions and advice are highly appreciate.

Best regards,
