I'm really beginner with FLUENT and I would like to inject particles, with a variable flow rate, from a face of my geometry (a simple rectangle) but I didn't even know how I should write my udf to do that. I tried something but it seems that FLUENT doesn't take care of my UDF. How can I specify from which surface I want FLUENT to inject particles ? I would be very glad if somebody could give me a model of a basic UDF to realise such a surface injection. Thanks for your replies ! Pauline
