Time varying spray cone angle
 
Hey experts

I'm simulating an injection and my spray cone angle varies with respect to time. I would like to know if any of you aware of a macro which can access cone angle quantity in fluent so I can define it as a function of time?

Alternatively this can be done by setting the cone angle to the small value (say 1 deg) and change the injection axis! however I still can't find a macro to access injection direction. even if somebody know this macro please let me know.

Tnx a million in advance

I answered you in the main forum.
Another way is to use "Journal" to change cone angle at each timestep automatically :)
It came to my mind just now :D
Goodluck
