Fluent User Defined Functions using Python

[abhishekchitwar]

Hi Team!

Idea is to support User-defined functions (UDFs) written in Python under PyAnsys-Pyfluent ecosystem.

This seem to be a good idea. This will allow use of single programing language. Many Python programmers will find it easier.

@abhishekchitwar Interesting thought, but probably a natural thing to ask about. Would you like the have the Python function executing in Fluent like a "C" UDF does today? i.e. in Fluent's host process and compute nodes?

If so, this could be quite a big job. It requires embedding a compatible Python interpreter directly inside the Fluent host and compute nodes, and defining APIs running locally inside Fluent to do things like you can do in UDFs currently (eg: loop over threads, cells and faces).

So, it would be very helpful if you could be as specific as possible about what you would like to do in such a UDF. Extending Fluent's expression language might be the better choice here depending on what it is you want to do.
