Subroutine

hI dear all!! I'm working on a simulation about drying kinetics of droplets. My issue is that the droplet is loosing water and I must tell the CFX to stop the evaporation at a certain point. How can I tell CFX to do that??? Perhaps using a subroutine???? Thank you very much to all

In CFX-Pre there is template for evaporating droplets. Did you check if it models your physics? If, yes, please try to explain what you intend to model an why the template is not enough.

Hiii and first of all thank you for fast reply.
I'm drying droplets that contain a certain amount of solids. In this case the diameter decreases until it reaches a critical value and it doesn't decrease no more. I have some experimental correlations on when this critical diameter is reached and I want to implement it on a CFX routine.

Where is the template that you're talking about???

CFX-Pre New case ==> Library template

or something like that. I have no CFX at my personal laptop, I can not check here.

Well, thats a challenge. Sorry, I can not help.
