Hi guys,

I need to simulate a windshield defogging system in order to define if my inlet flow velocity is enough for defog the whole windshield. I am planning on doing a CFD simulation on Fluent, I already have the cabin's CAD, however I am kind of lost on how to begin. I've read some articles on the subject but I am not sure how to set he BC for the fog layer, should I do a multiphase simulation, or fluent has another option for the type of problem?

I have looked here in the forum and did not find the solution for this problem, most of the post were unanswered, can someone point me into a direction please.

Thanks in advance.

Thank you very much, this will help a lot. You woundn't turn out to have the UDF file used on the tutorial would you? I am looking into the language used for fluent but I am still a little behind.
