Hi everyone,

I am working on a simulation that is divided into 2 cases, with different phenomena involved in each one.

My question is, How can I couple 2 Fluent simulations???

I have seen that this is not allowed with System Coupling in the Workbench.

Thank you in advance!!

If you really want two-way coupling you will require scripts and Start Fluent as Server or having a master and slave process. That is not a trivial work.

For one way coupling our a coupling which you manually you can use the profiles which can be written in one session /case and used in the other case.

 

If only thermal loads needs to be coupled at walls, System coupling can do that (with some expert env).

Thank you so much Mr. Amine for your help.

I'm working on a simulation wherein from case 1 I'll get the heat flux distributed over a wall surface. This info will be used to run a multi-phase case (case 2). From the latter case, I will take temperature distribution over the same wall and use it in case 1. And so on.

Which strategy do you recommend me to follow?

Thank you in advance!!!

If it is sufficient do that manually: Export the heat flux profile from case 1 apply it on the walls of case 2 and from case 2 export the temperature profile and use it in case 1. If you want to do that in automated ways every N iterations you require a lot of scripting (a sort of Master/Slave processes). 

Another alternative is as I said might be via using some expert parameters for System Coupling which are not supported and which I do not want to expose in this public community. 

Now what do you want?
