Transient natural convection, and immediately forced convection
 

Hi,
Help me please.


I want to model this transient case in Fluent:


Firstly, I have modelled Natural convection in a cavity with cylinders. Each cylinder has a source term. I have done it satisfactorily.
After a certain time, I want to model forced convection immediately after natural convection.


How can I save the initial conditions of the last step of the natural convection case in order to use them in the forced convection case? What could be another alternative procedure?

Run your natural convection case to your satisfaction. Change all the settings to your satisfaction for the forced convection case. Do not initialize it again. That's all.

Thank you so much LuckyTran. That works perfectly.
